[PyQt] Dialog Window's Position Offset

Thanks for the response Baz.  I'm trying to save a window's position 
when I close a window.  I would think that the position recorded on my 
last move event would be the one recorded on the window's close event.  
The fact that it is not points to an issue either with Qt, PyQt, or my 
window manager.  It isn't a good situation when you can't trust the 
pos() method for a window.  Since you're getting normal results, I'm 
starting to think that the window manager is to blame, not PyQt or Qt.  
FYI, I am on Red Hat Enterprise Linux v5.3 with PyQt v4.4.4 and Qt v4.4.3
