I'm having the same problem on my Mac. I will be typing fine in Word or Outlook, then out of nowhere my keystrokes stop registering. I can click and copy/paste with my mouse, but it won't let me type anything. Logging out and back in through logmein does not solve the problem.
I've found that if I hold down the control key on my Mac, it will allow me to type again, but this is an impossible way to type. I think the problem has something to do with the control key.
after opening a case with LogMeIn support, we tried one of their suggestions and while not ideal this did work. We had to change the Color options on the LogMeIn toolbar from HD to the middle color choice when connected in LogMeIn on the mac.
