I have to concur with Wade. I've been doing this for almost 15 years and have never run into this problem. Now I will be aware of it. So, not an idiot, but a "thank you" for exposing another problem area and suffering through the problem.
Come to think of it, I may have a system that I took out of service because I couldn't fix it... symptoms are very similiar to your's. Hmmmm, now if I can only remember where I stashed it....
