I've come across a minor bug on Maloria that closes my Graal Client, Not sure if the bug has been mentioned before or not so I'll just come out with it. If I open/close the start menu or attempt to use Graal in full screen mode my Graal Client will instantly close. The bug might be fixed in version 6 of the Graal Client and may also be operating system specific but have no way of testing it yet.
I'm using version 5 of the Graal Client running on Ubuntu Linux 10.04
