I would like to make my programm use the "system tray". I think, it is
the field right down on the Win95 taskbar where the clock is. My
programm should lay its icon there and if I click on this icon a menu
(icon of a programm and the name) should open similar to the deskmenu of
Microsoft's PowerToys.

How can I realize this???
