I started a new job last week, they want me to use Ubuntu as my dev environment, although that's about the only requirement.

I installed Windows 8, VirtualBox, and then Ubuntu. Ubuntu works great, and I don't have any complaints about the operation of Windows 8 either. But gnome3's HUD/Dashboard thing opens up uncontrollably. All I need to do is move my mouse and it opens. Other times I can be working for... minutes on end without problems.

Does anyone have any suggestions, or know how to fix this? Or well, anything? If this were Windows I would think some script kiddie was messing with me, but it's a default Ubuntu install (more or less).
