This is a known bug with win32-gui.
It is fixed by using perl 5.7 or later or using the circular ref patch
I posted to the list during the 1.02 release cycle. A similar section 
was applied some years ago, but removed because older perl don't allow 
circular refs at all.

Remember to DESTROY any dangling circular refs with perl <= 5.6.
