I recently purchased a Logitech Marble Mouse for home–since I was very happy with the one that I had at work. However, the new one has a quirk: the pointer will lock-up. Then if I remove the marble ball and re-insert it in the base, it will start working again– for 15 or 20 seconds, or so. I believe I have a bad mouse. But is there anyone who has any ideas on how to correct this problem? Any help will be much appreciated. This is most annoying! Thanks, Ken
