I have found that FireFox returns this problem much less than Internet Explorer does. Do what you feel best in that observation, but if it were me I would get FireFox and dump IE.
If this does not work, post to this thread so I will have some idea how widespread this problem is. I would also appreciate knowing if this fixed the problem so post that here as well.
Also, please post any problems you may have in this forum rather than emailing me. I get 2-300 emails every day, mostly spam, and you will get a much faster response by posting here rather than emailing me through the "Contact Us" link.
And, for the person that chose to cuss me out for not devoting 100% of my time to catering to your every need, I decided to just to revoke your membership, rather than work with you to resolve your problem....
