Hi guys,

I've googled and searched this forum for an answer to this problem but to no avail.

If I alt-tab out of DOSBox, then when I return to DOSBox, it behaves as if the up arrow key is being held down.

This occurs in all games and even in just the base operating system. I can solve the problem by simply pressing any key on the keyboard and DOSBox immediately stops behaving as if the up arrow is being pressed, but it is somewhat annoying to have to do this when I alt-tab.

The bug seems to occur randomly, about 50% of the time I alt-tab. It makes no difference whether I'm running in full screen mode or windowed mode.

I'm running DosBox 0.74 on Windows 7 64bit. I've tried running DOSBox in compatibility mode for XP, and I've also tried running the core in all 3 modes but this hasn't solved the problem.

Any ideas on how to fix this?

Thanks guys,
Dave.
