JWeekend, that's why I made a Quickstart... (-; Unfortunately, I'm not able to demonstrate the problem. My page works fine in the Quickstart. It doesn't in my application. I know you're going to say I have to add more "seemingly unrelated code" until I hit the problem - but my application is not very large and I ended up adding the entire thing to the Quickstart - and I still can't demonstrate the problem.
This is a weird one.
