the only time I've had unleashX crash, and this was repeatable every time, was when I put a particular preview video in my DOAX Volleyball game folder, and used a skin which supports video preview of games.
when I went over doax in the menu, unleashx froze hard every time. delete the video, works perfectly (and works with all my other preview vids) so its a fault of the particular video I guess. though would be nice if it just didn't display the vid if it was corrupt, instead of crashing but eh..
so the only thing I regularly launch evox for is when I want to launch a game with an evox trainer. otherwise unleashx does everything I need. so if it supported evox trainers somehow that would be awesome and I'd never need another dash ('cept ms dash or thc dash to mess with savegame memory stuff)
oh, and one tiny little thing -
the ftp server, I wish it gave you the current free space on the drive when you do an ls or transfer a file or something, the way evox ftp server does.
