Yes I searched the forum for info on this.

When I uninstall Canola the app is still in extras. I am not able to remove it using the control panel navigation app. Interestingly when I used the application manager to uninstall it didn't completely uninstall - but the app manager thought it was. It was still running (checked using ps in cterm), So I reinstalled and uninstalled using apt-get. This completely removed it from the system - except it's still listed in the extras.

Any ideas?
