If an application in its IDropTarget::Drop() implementation saves the passed in
IDataObject and later calls IDataObject::GetData() it fails because global cached
data is no longer available. Another solution is to create a copy of global data
and save it inside of IDataObject, but since all data including item contents is
global anyway this doesn't seem worth the trouble. Global cahed data will be freed
in next X11DRV_XDND_EnterEvent().
