When switching workspaces in Ubuntu 10.10 it automatically shrinks the window to be very small. Other times when clicking on the window it randomly shrinks as well.
Preferences has crashed a few times. Memory errors when setting a preference.

Advanced functions. I use it primarily just for simple FTP upload/download.
