IntelliPoint

 * Microsoft's IntelliPoint mouse software can cause numerous display (GUI) glitches in several Adobe (and other) products. In Premiere Pro the workspace windows will "jump" or "jiggle" a few pixels and then return to their original location, especially when bringing up menus.
 * Uninstalling the IntelliPoint software via the Control Panel's Add Remove Programs fixes this problem.

Updates

 * Microsoft released updates 886716 and 885222 to address problems caused by SP2.
