The return value processing for SetCapture was in error (it was treated as a
boolean function, so would always return None, or raise an error when there
was no previous window that had captured the mouse).  I have fixed that bug
here.  For now, you can simply catch that error and ignore it (the new
version will simply return 0 in that case)
