Anyone have this problem? Everytime I run Descent 1 or 2, as soon as I click any mouse button, it dissapears off the screen and I can't change any options. I've tried using the "ctrl f10" trick, and it brings the mouse pointer back, but, when I click any mouse button, it dissapears again. I've had this problem on 2 computers, one running XP, one running Vista 64. Anyone got any ideas? Thanks.

edit the configfile of dosbox
change autolock=true to autolock=false
