Yes, that happens to me as well. I always am able to resolve it by pressing the control key once or a couple of times. It's almost like the control key is toggeling in to a mode where it adds itself to what ever key you are pressing. I am stubbern enough to make it work but so far, not stubbern enough to care why it happens. Best regards... Rich Letourneau Work: 306-761-4275 Home: 306-352-3052
