I have found a bug in the new release, hopefully it can be fixed soon. When I position the dock in the lower left corner of my screen, so the center icon looks like the start orb, and I click the center icon to open start menu, as soon as I move my mouse, the menu disappears, and I am unable to use it. Actually, I just noticed, if I set it to toggle anywhere on bottom of screen the problem continues. Anywhere about 3/4 of the way down my screen. I'm running Windows Vista Home Premium SP1.
