System Tray doubleclick

Hi,

I'm programming a software that goes in the Windows Systray. Everything is ok but one thing doesn't work.

When I doubleclick on my systray icon, I want to show my app. The app appears but only when all windows are minimized and when the app popup, it is not focussed and the title bar is flashing.

How can I show my app and focus on it after doubleclick?

It works fine when I do a popup menu with the right click on the icon but not on the doubleclick!?

I tried many many many things and nothing works :
Form.Show
Form.Visible = True
Form.SetFocus
Form.ZOrder

Can anyone help me?
