I run Windows XP in Coherence mode. Fairly frequently (several times each day) when I switch back to a Windows app from a Mac app, the Windows act behaves as if a modifier key (typically the control key) is stuck. In order to un-stick the key, I have to switch to a Mac app and then back to my Windows app. Any idea why this is happening or how I could prevent it? I have seen this problem ever since upgrading to Leopard, and possibly before.
