Your suggestion about disabling the mouse for Win 3.1 made a difference. I don't know enough about hardware to comment about the emulation. I know that original Wing Commander runs too fast on at386 to be playable, but WC Privateer runs slow and choppy on at586. That series always was a pain in the ass to get running when they released them. Every other DOS game I have seems to run fine on at386.
