Hmm, thought I had replied to your note but it's not appeared.

So I added "warnings;" in to the code but it revealed nothing on my system, no complaints or anything, which is of concern since you indicated that you had issues, but I tried again anyway and got the same problem.

I took the code for creating the menu from win32-gui-demos.pl on CPAN and just pared it down. This menu is designed to be used as a standard Windows menu but as far as I can tell pop-up menus are created in the same way.

I should have said that I am running ActiveState Perl v5.16.3.
