--- Comment #205 from Roderick Colenbrander thunderbird2k@gmx.net 2007-10-28 06:37:55 --- I'd like to point out that the child window bug is not fully over. The new child window backend is not used on toplevel windows which causes bugs like the one in weatherscope where the menu is overdrawn. This should fixed in the future.
