I noticed a small problem: my taskbar is set to auto-hide. If I view an image full-screen in IrfanView (Enter on keyboard), and press the Windows key, the taskbar doesn't appear, while the Start orb sometimes does (over the image), and sometimes doesn't. Start Menu always opens, but again, sometimes it appears in it's normal place (above where the taskbar should be), and sometimes it appears right at the bottom of the screen. Happens with both 1.2 and 1.3rc0.
