Yeah, the same thing's happening to me. It usually starts after I've downloaded at least twenty or thirty megs, and continues until I've removed all incomplete files which were initiated during the session which caused LimeWire to crash. All crashes are accompanied by a fragmented cursor, as Limewire disappears completely, revealing only the desktop's background, but no icons or menus.

Occasionally, there will be an error of type 10 displayed, but more often than not, no answer is given, and I am required to restrat the computer. :\
