Composer crashes when dragged to a second monitor

[cyana]

Dear SimLab,
I experience regular crashes when I drag Composer to a second monitor. Mostly they happen when about 90% of the Composer window has reached its desired destination on the second monitor:

I found out that you can avoid the crash, when you drag the window of the object tree and the window of the object attributes separated from the main window. So, first you have to 'loosen' the tree- and the object window so they don't move with the main window. Then drag the main window, and after that the tree- and object window to the second monitor.

Thanks
