Re: Handle being created when I don't expect

    Also, if it helps I hacked my code to not crash when the
HandleCreated is called early and I notice the these
additional problems right away:

* When opening the first MDI child, that window does not get
an Activated event like it used to.  If I open a second MDI
child and toggle between them then the Activate gets called,
but with one MDI child the Actived event is skipped.

* There seems to be a focus/current problem because if I
have MDI Child #1 active I can click around in it and see
the mouse clicks have the normal effect but when I press
Ctrl+F2 that keystroke appears to get sent to MDI Child #2
instead.

   I update my mono installation from SVN source every
couple of days and all of these items were working as of a
few weeks ago.

Could you execute with "mono --debug app.exe" so
that you get line numbers as well? And knowing which version
of Winforms you're using would also help
