My setup is Parallels Desktop with Windows XP, Service Pack 3 on a Macbook Pro. After tabbing between Parallels and Mac, when in Windows every key I press seems to perform a windows shortcut. For example, L logs me out, m minimizes all the window. I've been searching through forums haven't found any solutions. This happens only after I do tabbing between Parallels and Mac and this happens with and without an external keyboard.
