Hi Mike,
I ran into the same problem and the easiest way I came up with was just by
forcing the window to be destroyed every time the script ran.
Just like you would do in the old days with mel :)
if pm.window( 'testWindow', query = True, exists = True ) :
pm.deleteUI( 'testWindow' )
So add those lines to your script and that deletes the old window.
