Strange modal form behaviour

[cold80]

Hi guys, it's a little problem but I'm quite stuck with it. I'm
developing a Windows Forms application with VS2008 and I have noticed
this little graphical bug. I have a main form with ShowInTaskbar=true.
I open a modal form (with showdialog()) with ShowInTaskbar=false.
Then, just sometimes, when a use the "Show Desktop" icon or I change
the active program when I go back to mine I can see just the main form
(the modal form is somehow hidden) and obviously it's locked, I can't
interact with it. Neither I can see use the modal form because it's
hidden, so I have to change the active program with ALT+TAB and the go
back to my application. With this move I can get back my modal form
and can continue working. How can I avoid this and keep my modal form
"hidden" from the taskbar?

Thank you in advance for your help

Try using the ShowDialog() overload that sets the modal form's owner, e.g.
modalForm = new ModalForm();
modalForm.ShowDialog(this);
