Hi all!
We have two laptops. They both are Win7Pro 64bit downgraded from Win10 Pro.
On mine (#1 for this conversation), one of the things we installed was D-Fend Reloaded (normally for Vista and up--to user profile). I also have McAfee (Preinstalled 30 day trial), Malwarebytes Anti-Malware Free (currently in the 14 day free trial of Premium with on-access scanning, start when Windows boots, etc--unchecking the "protect MBAM from malware" option made no difference--error had already broken it?), and Malwarebytes Anti-Exploit (also in the 14 day free trial of Premium).
On #1, at 1:28 PM (local time) Dosbox went fullscreen successfully. Later, (at 9PM)--without knowingly changing anything other than travelling to a different "home" wifi network, updating MBAM to the latest definitions and Steam auto-updating on Windows boot and maybe hitting the "Insert" key which has been remapped to now be "Pause/Break"--when I tell Dosbox to go fullscreen, it starts the process to go fullscreen, crashes to minimized, and eventually exits Dosbox. It is the exact same problem as mentioned here Updating to the newest D-Fend Reloaded did no good.
Since I had made a bunch of changes since my last macrium Reflect backup (a few days before) I entered Safe mode and system restored to when Dosbox worked (1:28PM).
The other laptop (#2 for this conversation) has exactly the same problem, except that the bug started occurring after updating some Lenovo Drivers (and MBAM?). In order to fix it, I had to run System Restore. At the time that #2 didn't work, #1 did. After making some changes and getting Dosbox to work on #2 (removing MBAM via revo, and than Malwarebytes Clean uninstall, and maybe something else), Dosbox on #1 did not work.
Obviously, I can't keep restoring my Macrium backup whenever I want to run a Dos program in fullscreen.
Dosbox graphics is set to Graphics>Surface (Graphics>Overlay does not seem to work).
Please provide guidance and suggestions! I really, really want it to work!
These relatively pricey (for us) Lenovo laptops should be able to run a program that our (cheap in comparison) Lenovo H215 tower (OS: Win7 Home Ultimate 64bit) has successfully run for years (though without MBAE installed). Just checked, the H215 still opens Dosbox fullscreen.
Thank you!
PS:
D-Fend is the same installer I have used previously on several PCs--"D-Fend-Reloaded-1.2.1-Setup.exe" downloaded in 2012.
GPU= Intel HD 530 and nVidia Quadro M2000M (4GB) D-Fend runs by default under the iGPU; switching to the dGPU made no difference that I could see.
CPU= i7-6820hq
16GB DDR4
Event viewer on these laptops says (under System:) "Event ID 245: win32k application dosbox locked the primary surface"--when it works it finishes that quote "...surface 1 time(s)"; when it does not work (crashes) it says "win32k application dosbox locked the primary surface 2 time(s)"
On the H215 (D-Fend Reloaded installed for 3 years) under EventViewer>application it says ID 9010: "A request to disable the Desktop Window Manager was made by process (DOSBox DOS Emulator)", but >System says nothing about the win32k application.
Is it something where adding an exception for dosbox or D-Fend to MBAM or McAfee would solve it? Will it resolve itself when MBAM ends its trial?
Thanks!
