MDI form -- hung up when show new child form again

[Ryan Liu]

Hi,

I have a strange problem.

I can open child form(s) in a MDI container for the first time.

I can still open and show new child forms as long as there is one child form
in MDI container.

But if I close all forms, then I can still construct a new child form, but
as long as I call form.Show() or form.Visible = true, the program hungs up.

Can someone help on this?

Thanks a million!
Ryan

Possibly. If you post a concise-but-complete example program that
reliably reproduces the problem, someone may be able to comment on your
problem.

Otherwise, the likelihood is low (though not zero).
