Probably it bothers only hardcore keyboard users like me
Anyway, if you switch to another application with a modeless window still opened (e.g. search results) with the taskmanager (Ctrl-Tab) and try to switch back to it the same way 2x completely "disappears". Well, not completely, since you can make it reappear with the mouse and the taskbar.
Strange behaviour though. OS is still Win98SE BTW.
