I had a script whose NotifyIcon worked fine under version 0.0.580 of
Win32::GUI that no longer works since I upgraded to 0.0.670. It gets

does not get anything when you click on one of the items on the menu.
I had a similar problem that Glenn helped me with on this list. I solved
it by adding a call to DoEvents after the call to TrackPopupMenu. My
theory is that the menu object was kept in scope in .558, but not in
.670. So the call to DoEvents gets the event handled before the menu is
destroyed.
I'm glad you recognized the symptoms on this one were the same, Johan.
Since they were not my symptoms, I guess it didn't click for me. But
indeed, it seems that scoping is the culprit. I couldn't say what is
different about the versions that causes the scoping difference, but
clearly something is.
So I will augment your solution suggestion with my other one, which is
to keep the menu in scope, in your own code, by promoting the pointer
returned from MakeMenu to some more global context. As I recall, your
very dynmaic menus made the call to DoEvents an easier solution for you,
but for programs with more static menus, keeping the pointer around is
probably the more appropriate solution.
