Thanks Geoff!

I know people are impressed by the responsiveness of this list, but this is
the first time I've experienced a problem being solved before it was even
discovered! I moved the calls to my initialisation and finalisation code
into MainForm.FormShow and MainForm.FormClose and never even saw the
problem you discovered.

As for my original problem, it appears to have disappeared with 4.2 HcTest.
So thanks to Geoff, Marco and Jason for fixing whatever was wrong.
