Form Closing on its own

[Daniel]

OK, this is bizarre. I have used this method many times before and it
never did this. The code is:

Dim myFrm as New Form1
myFrm.ShowDialog()

Normally, this opens the form and freezes the calling one until myFrm
closes. However, not any more. The form opens. I interact with it and
then it goes off on a long process. When finished, it closes itself and
the previous form becomes active again.

What on earth is wrong?? Thanks!

Maybe you set the dialogresult property of the button starting the long
running process?
To find out the cuase: Set a breakpoint in the Form's Closed event and, when
it's reached, have a look at the callstack.
