hello everyone

I have a REALLY BIG problem with dosbox 0.73 and I really hope you can help me.

when I play a game under dos box (i tried EXTREME PINBALL, PINBALL FANTASIES, SANGO FIGHTER, FIRE & ICE and many more games...) and after a while I want to quit, so I press CTRL+F9

and then the problem start

when I press CTRL+F9 the game freezes, BUT I cant see the desktop, the game is stuck when i press CTRL+ALT+DEL I get the WINDOWS TASK MANAGER but not in windows resolution, I get it in the game resolution

when i press thw "WINDOWS KEY"+D i cant see the desktop because thew game is in front

so at the end I MUST RESTART!!!

This is really annoying problem, it happens 90% of the time i have no idea why sometime it work and sometime it crash

I tried to change the outoput in the dosbox.conf to SURFACE then I tried DDRAW, and then I tried OPENGL, BUT THEY ALL STUCK MY WINDOWS

I put you here my dosbox.conf please help me solve this nightmare:

all my games have the same dosbox.conf

# This is the configurationfile for DOSBox 0.73.
# Lines starting with a # are commentlines.
# They are used to (briefly) document the effect of each option.

# fullscreen: Start dosbox directly in fullscreen.
# fulldouble: Use double buffering in fullscreen.
# fullresolution: What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
# windowresolution: Scale the window to this size IF the output device supports hardware scaling.
# output: What video system to use for output.
# Possible values: surface, overlay, opengl, openglnb, ddraw.
# autolock: Mouse will automatically lock, if you click on the screen.
# sensitivity: Mouse sensitivity.
# waitonerror: Wait before closing the console if dosbox has an error.
# priority: Priority levels for dosbox. Second entry behind the comma is for when dosbox is not focused/minimized. (pause is only valid for the second entry)
# Possible values: lowest, lower, normal, higher, highest, pause.
# mapperfile: File used to load/save the key/event mappings from.
# usescancodes: Avoid usage of symkeys, might not work on all operating systems.


# language: Select another language file.
# machine: The type of machine tries to emulate.
# Possible values: hercules, cga, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe.
# captures: Directory where things like wave, midi, screenshot get captured.
# memsize: Amount of memory DOSBox has in megabytes.
# This value is best left at its default to avoid problems with some games,
# though few games might require a higher value.
# There is generally no speed advantage when raising this value.


# frameskip: How many frames DOSBox skips before drawing one.
# aspect: Do aspect correction, if your output method doesn't support scaling this can slow things down!.
# scaler: Scaler used to enlarge/enhance low resolution modes. If 'forced' is appended,the scaler will be used even if the result might not be desired.
# Possible values: none, normal2x, normal3x, advmame2x, advmame3x, advinterp2x, advinterp3x, hq2x, hq3x, 2xsai, super2xsai, supereagle, tv2x, tv3x, rgb2x, rgb3x, scan2x, scan3x.


# core: CPU Core used in emulation. auto will switch to dynamic if available and appropriate.
# Possible values: auto, dynamic, normal, simple.
# cputype: CPU Type used in emulation. auto is the fastest choice.
Show last 169 lines
#            Possible values: auto, 386, 386_slow, 486_slow, pentium_slow, 386_prefetch.
# cycles: Amount of instructions DOSBox tries to emulate each millisecond. Setting this value too high results in sound dropouts and lags. Cycles can be set in 3 ways:
# 'auto' tries to guess what a game needs.
# It usually works, but can fail for certain games.
# 'fixed #number' will set a fixed amount of cycles. This is what you usually need if 'auto' fails.
# (Example: fixed 4000)
# 'max' will allocate as much cycles as your computer is able to handle
# Possible values: auto, fixed, max.
# cycleup: Amount of cycles to increase/decrease with keycombo.
# cycledown: Setting it lower than 100 will be a percentage.


# nosound: Enable silent mode, sound is still emulated though.
# rate: Mixer sample rate, setting any device's rate higher than this will probably lower their sound quality.
# Possible values: 22050, 44100, 48000, 32000, 16000, 11025, 8000, 49716.
# blocksize: Mixer block size, larger blocks might help sound stuttering but sound will also be more lagged.
# Possible values: 2048, 4096, 8192, 1024, 512, 256.
# prebuffer: How many milliseconds of data to keep on top of the blocksize.

# mididevice: Device that will receive the MIDI data from MPU-401.

It must be a problem with your videocard drivers. Do you have it up to date?

What video hardware do you have?

Intel i7 5960X
Gigabye GA-X99-Gaming 5
8 GB DDR4 (2100)
8 GB GeForce GTX 1070 G1 Gaming (Gigabyte)

thank you

I don't have Windows, but why not try the Escape button or whatever exit mechanism the game used back in its original dos days. In the dos prompt after exiting the game, type exit and hit enter. DOSBox should close cleanly.

Just using ctrl+f9 would be like hitting the power button on your dos computer 20 years ago. Maybe the video mode (or whatever) is what is "getting stuck" and you can avoid this with DOSBox exiting cleanly?

You are 199k RAM short of having enough memory.
You need to buy more memory or remove any memory resident programs, Dude.

So today I played DIGGER at full screnn and press CTRL+F9 and the windows stuck again!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I need your help, I can`t stand it anymore, it happends randomly so I cant find the reason whats wrong

My computer is quad core with 4 gb of memory so I cant see why this problem happening

I think that if I will press ALT+ENTER (go to window mode) and then press CTRL+F9 the windows wont get stuck BUT I HATE THIS WAY!!!

I want to quit the game in 0.1 seconds

Please help me...🙁

dj_anubis, is it really necessary to use machine=vgaonly for the games you play? Does the problem also manifest itself when using the default setting, machine=svga_s3 ?

Boot your windows in safe mode and try to replicate your issue.

If it works then you have a driver/video card hardware problem.

well my friends, it has been long time since i poster this thread


even though I am using DOSBOX 0.74, created the conf file with config -writeconf dosbox.conf

even though I updated yesterday my nvidia drivers

the problem happends again

let me explain whats happen

the game itself runs perfect until the moment I try to exit IT DOESNT MATTER IF I PRESS CTRL F9 OR QUITING THE THE GAME MENU if i play more then 3 -4 minutes the game will freeze

Then when I press ctrl alt del I can see only the taskbar in the game resolution

and I have to PHYSICALLY press on the RESET button

any ideas how to solve it?

Check your system (overheating etc.), if a usermode application can bring
your OS down it's pretty broken already. Not related to dosbox.

Your system is ok? How did you test that? In-depth memtest, stress graphics benchmarks?

Guess you already tried the suggestions posted in this thread, like what DOSFreak asked you to do.
