No, the problem that's being discussed, is that if an app isn't closed
properly, it doesn't issue the "remove from tray" code, and hence the
tray never gets updated. Moving the mouse over it forces it to update,
and therefore removes the orphaned icon. You can try it yourself-- run
some useless program that uses a systray icon(aren't they all?). Now,
kill it with task manager, and look at your systray-- the icon is
still there. Move your mouse over it, and watch it disappear...
