I have one bizarre problem with the new claws-mail on the N800: I can't exit it.. the program works and all, but clicking the X in the upper right corner does nothing, and there's no menu when I click the upper left corner (where I would look for an 'exit' option). Clicking anything else works, and I can do the mail stuff. But to quit the program I always end up having to start an xterm and kill the pid from there.

Another problem is that it's tricky to open a message.. I have to try some 4-5 times usually, and most of the time claws-mail wil just split the screen vertically for a second, then go back. But when the message opens things are ok.
