When I use DOSBox, everything works great, until I have say, space combat in Starcontrol. I cannot hold down multiple keys, as it seems the max is 2 (!). It has done so with several games, and it is not my keyboard, as I play many FPS' online, which require 3+ keys to be held at once.

I have:

Radeon 9800pro
ASUS a7n8x-e
Soundblaster Live! 5.1
1 gig ram
Windows 2000
