I have a week old 8700c and the escape button seems to hang and not operate right. I don't think its a hardware issue because if I roll the trackwheel and hit the escape button it works. For example, if I want to close the messages screen and click escape it does not work everytime, but scroll down one message and escape it does! Could it be the OS or what?

Any thoughts?

Have you tried removing and replacing battery? Just a thought.

Actually, I took you advice and removed the battery and replaced it and now the buttons actually seems to "click"...you might have fix it.

I will keep posted. Thanks.
