[IronPython] Problem Closing Application

Hi
No if I run that code - and I am presented with the MainForm form, when I
hit the close button on the top of the form - the application is still
running in the background. If I try to close the Log_In form
programatically, instead of just hiding it, the whole application closes -
without letting me go the MainForm form.
So not to sure how to accomplish this - have spent quite a lot of time on
the net trying to get the answer - to no avail. Hope that you'll be able to
resolve this issue for me, as I'm stuck in my project, until I can get this
right!
Regards
Anthony
