Keystrokes lost since upgrading to Lion
Since I've upgraded to Lion I'm experiencing a rather odd problem: iWork doesn't respond to certain keystrokes. The worst offenders are Cmd-C, Cmd-V, and the like, but sometimes regular typing just doesn't appear in the document.
This is an intermittent problem: if I click on a Finder window and then back to Pages (or Numbers, or Keynote) then all is well once again – for a few minutes. Then, sure enough, when I try to Cut or Paste, I have to do it from the menu: the keyboard shortcuts won't work.
Anyone else seen this? Any suggestions how to track down what's causing it?
