I notice there are(and have been) quite a few queries on this topic.

I think this would be a candidate for the CodeBank ?

I think something as simple(to use) as -
Icon loads into systray on Form_Load.
When user clicks the Icon it shows the Form, if not showing.
It hides the Form if it is showing.
It has no right click popup menu.
It does not require double click
The Form never shows in the Taskbar.

Just click to show Form, and click to hide Form.

No menus (although a hidden popup menu in design mode, may be required to get it working ?)

Is anyone aware of an example like that ?
