I'm working on a program that, when launched, displays an icon (a
Win32::GUI::NotifyIcon object) in the Windows taskbar notification
area-often referred to as the "system tray". When one of the buttons on my
GUI is clicked, a separate "worker" thread is created so that my GUI remains
responsive while a background task executes in the other thread. Everything
is fine up to that point, but when the thread eventually finishes, my icon
disappears from the system tray and I get the following three lines of
Attempt to free non-existent shared string '_NotifyIcon1', Perl interpreter:
0x1cfc6f4 at C:/Perl/site/lib/Win32/GUI.pm line 3429 during global
Unbalanced string table refcount: (1) for "" during global destruction.
Unbalanced string table refcount: (1) for "DELETE" during global
I'm happy to post my code, if necessary, but I thought someone might be able
to quickly tell me whether Win32::GUI::NotifyIcon is thread safe.
