Is it by any chance a USB keyboard or KVM switch? I had a similar issue a
while
back (not specifically in MAME), where a 2 x PS2 --> USB converter
evidentally had troubles
keeping up with sustained rapid keypresses.

Cheers,
Brett

No, just a standard PS/2 KVM switch. Not a USB port in sight!

Like I said, I've not had any other problems with any other Windows app or
game. Do you think that maybe Mame requires a different rate of input from
the keyboard than a standard Windows app would?

Thanks for your reply!
Dave.

This was my initial reaction to the post as well. We actually have a
old one at work, not even sure who makes it but it is at least 8
years old and its the only one I dont have issues with. The newer they
are, the worse they seem to be. This is all IME, so YMMV.

Your conscience never stops you from doing anything. It just stops you
from enjoying it.

I have an IOGEAR KVM that works perfectly in almost all respects, EXCEPT the move forward key "W" cannot be used continuously in any game, for example driving or running forward it stops after a few seconds, requiring a rapid tapping in order to keep going, and in playing games like Far Cry 2 or Modern Warfare 2 it is impossible to drive fast enough to avoid serious problems (like death).

I thought it was a computer problem until I saw this thread and realized it is the KVM. Anybody know of a fix other than disconnecting from the KVM to play games?
