Minimize application (from 2nd form)

Hi

I have an application where the customer complains about the way it
minimizes, the problem occus whe I have opened (created) a 2nd form (from
the MainForm) - if the user then clicks minimize on the 2nd form then the
form i minimized and is shown just above the taskbar.
I have tried to capture the Application.OnMinimize however that only gets
fired when it's the mainform that gets minimized.

Is there a way I can capture some form message and to send a minimize
message to the mainform? Or something else like that?

regards
Henry
