I have a WinForm program that checks a database for changes, and if there are any, it will open another WinForm telling the user what is happening (the popup WinForm has some special functionality making a MessageBox insufficient for this task). Each time one of these popup WinForms shows up, a new icon shows up in the system tray and does not go away even if you hover over it (this isn't a tray refresh issue).
What I'm wondering is how to get the popup WinForm to display no tray icon at all.
