So I was thinking about maybe getting the desktop file manager addon so I downloaded the sample one from http://xfilesharing.com/
Program installed fine, I launched it and it told me I needed to login, I used the default admin:admin login just to test it so I didn't have to sign up. I tried to upload a couple of text files just to see how nicely it worked, nothing happened, then the program crashed.
Reopen the program and it instantly crashes. Uninstalled it, reinstalled it and the issue still persists (perhaps something in the registry isn't unset after removal?).
