The system lock has nothing to do with being part of domain. It is a setting in your screen saver, so you should be able to try it at home.

True, I'll look into it once I get home.

Locking might seriously screw up the timer, maybe pause dosbox before
leaving the pc.

I tried this just now and while it didn't crash, the Dosbox screen gets all messed up when you unpause it.

update graphics card drivers, try different output= settings etc.

Dosbox runs fine in this system, its when I paused Dosbox and locked the desktop that this happens, so not sure if video drivers have something to do with it.

well try it and see

overlay output?
I already reported this once...if screensaver is activated or desktop is locked, SDL_LockYUVOverlay will return NULL. DOSBox does not check for valid pointer before writing to overlay...

Ebf18, open "dosbox.conf" in your DOSBox directory with a text editor, and look for the line starting with "output=" (near the beginning of the file). Try some of the values mentioned in the comment block above that line. I'm using "ddraw", because it works best on my system.
