I thought closing the whole application was what you wanted to do? In
your original email you asked:
The program runs fine - except that when I close the MainForm form
- the application is still running. I know it's because a login.py
object is hidden. What I'm asking is how construct the programming in
such a way that this does not happen - that when the second form is
closed - the application closes;
So now the application closing is a problem?
All the best,
Michael
