yes, for instance when i have a clock on the desktop (so the icon is null and 
displaying the clock instead) i click on the clock and the popup is shown but 
it doesn't seem to be a window, but the Plasma::dialog containing the extender 
seems to be on the scene, the transparency of the border is disabled and 
clicking away doesn't make it disappear (and thinking about a view embedded on 
the same scene it displays it's a bit scary idea :))

another problem:
adding a clock on the desktop when plasma is already started produces a crash, 
at line 389 of extenderitem.cpp widget->setParentItem(this);
don't understand why just setting a parent item would crash :-/
instead if the clock is saved in plasma-appletsrc it gets created without any 
problems
