upx has to be run from console. You navigate to the folder it's in, then type the command "upx programname.exe" [obv. substituting the name of the thing you want to compress] and hit enter to see it go. Why would compressing the exe ever be a bad thing? There's a bit about dll's, how if you compress those they can't be shared by diff programs, but that's irrelevant.
Furthermore I can't irc tonight because stuff.
