Since posting my original message I haven't seen the 'parking window' again!
However for compeltenes my handling of the message is below.
Perhaps I should call the Base method in the case of WM_ENDSESSION
protected override void WndProc(ref Message m)
{
if(m.Msg==0x001 1) //WM_QUERYENDSESS ION
{
mainForm.shutDo wn = true;
Trace.WriteLine ("Shutting Down - TrayIcon WndProc");
mainForm.Show() ;
MessageBox.Show ("You must close System5 Logger before shutting down");
}
else if(m.Msg==0x001 6) //WM_ENDSESSION
{
mainForm.shutDo wn = true;
Trace.WriteLine ("Shutting Down 2 - TrayIcon WndProc");
}
else
base.WndProc(re f m);
}

Nicholas,
There is such a hidden window created by the Framework - you can find it
with Spy++ (or a similar tool). Looks like it becomes visible under some
circumstances. The author should probably post more details on how s/he
handles the WM_QUERYENDSESS ION message.

When I use the WM_QUERYENDSESS ION event to prevent closing of my app when
Windows is shut down, I get the 'windows forms parking window' appearing
which is very confusing for users.
Any ideas how to stop this?
