 Yes i see the problem..., but i don't think adding the expanded taskitems
 to the mainlayout would be a good option, because we cant give the expanded groups a distinctive
 layout with a color then. 
 We could move the expanded group to the next line if there isn't enough room for it,
 but this is probably mostly irritating if everything moves around.
 
 Another idea would be to "zoom in" the group, so only the expanded group is visible
 (and a return button or something). So normally one would use the expanded group popup,
 and if you currently work solely on a certain set of tasks you can expand it and everything else dissapears.

I couldn't reproduce this error yet.
But currently i'm having an even worse one. All
WindowTaskItems and TaskGroupItems don't have a text anymore, 
although the tooltip is fine.
