Mac: OnExit not called for my app

Hi,

On mac when my app is quit by right clicking on the dock icon,
wxApp::OnExit() and ~wxApp() are not called. Rather NSApplication is
calling directly to exit() which starts to do global cleanup.

The strange thing is that it's working fine when I create a minimal sample.
But the stack trace below shows the problem.

~TjnVirtualMemoryManager is the destructor of a global object for which
I've set a breakpoint. Why is NSApplication calling exit() rather than
returning all the way to stack frame #26 where OnExit would normally be
called? Any help appreciated, thanks!

Hi Joost

And your app does have a proper 'Quit Application' menu item ...

Best,

Stefan
