I was attempting to add another override for a program (C:\StarCraft\starcraft.exe), however, when I selected the "Emulate Virtual Desktop" checkbox, winecfg freezes. There is no CPU usage, and there is nothing trown to the console. I am using Linux 2.6.14-gentoo-r3, and the slackware 10.2 binary build of wine 0.9.4 without debug symbols. The latest version of wine available for my distribution is the very last alpha release (20050925, IIRC).
