This is a known bug with win32-gui. It is fixed by using perl 5.7 or later or using the circular ref patch
Ok - I've created a tracker item so this issue isn't lost:) https://sourceforge.net/tracker/index.php?func=detail&aid=1248578&group_id=16572&atid=116572 I've just ran that example under 5.8.7 and it still crashed?
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.
I just searched the archive but it doesn't show any attachments - could you forward it again so I can see if it fixes the problem?
Cheers, jez.
