--- Comment #5 from Caladan a.vankaam@chello.nl 2010-06-26 00:36:05 --- tested with RC5, still happens.
tested with nvidia drivers 196.x and 256.x, same behavior.
tested with Opensuse 11.3 RC1 which has KDE 4.4.3, just in case it might be related to KDE, the behavior is a little different, the mini screen top left appears, clicking that will fill left half of the screen with lotro, right clicking taskbar and selecting full screen will give lotro fullscreen but like before without mouse/keyboard input, ctrl+f1, ctlr+f2 will eventually solve this.
