CTRL+F12 stops working

Hello,

I have noticed that with the various versions of DOSBox I have tried (0.70 - 0.72), the CTRL+F12 key combination (for increasing CPU cycles) occasionally stops working. It won't work again until I have logged out of Windows and logged in again. Weird indeed.

I have no idea as to what could be causing this, but I figured maybe other people have this problem as well. Maybe it's a bug.

I am using Windows XP SP2 and a Logitech "UltraX Media" USB keyboard. I have no other programs running that capture keyboard input.

(It may be worth pointing out that my Logitech USB mouse doesn't work properly in specific combination with Daggerfall, either. The keyboard thing applies to all games and apps, even just the DOS prompt.)

Cheers,

Garg

Try hitting the ctrl and alt and shift keys a bunch of times if this happens,
most likely one of them is stuck.

Thank you for your reply, but both CTRL keys are fine.

Hope the keys know this, too.

The obvious thing to do for testing is trying with a different keyboard.

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

Or easier, open notepad and press CTRL-F4. This should close Notepad, If not then you have a broken key on your keyboard.
Could also F12 that is broken as you say the other combinations CTRL-F11 are working.

To test this open MSWord and press CTRL-F12 then the Open Dialog should be shown. If not the F12 key is broken.

I apologize for the ambiguity of my posts above. I tested the keys and their possible combinations in other apps, of course, and they worked. That's what I meant to say when I wrote they were fine.

I understand you guys get a lot of dumb questions on these forums and I appreciate your effort (I am very grateful for DOSBox), but there was no need to get snarky. I just wanted to report a possible bug.

Nobody said it was a dumb question. And, as already posted, next time it
happens press the state-changing keys (alt/shift/ctrl and the lock keys)
a few times and see if the effect vanishes.

I'm almost sure that this problem is caused by another program running in background. I also tought this was a bug, but it was caused by (mis)configuration of hotkeys in Miranda.
