I've had the same problem on a few boards using this software/system. I think it has to do with pages being refreshed more than once or some junk like that, makes it disappear.
Rob, I can't stop myself from cracking up. This is no reflection on you, but I couldn't help but notice that right under your last post where you were saying something like "hmm.. now it works. intermittant.." there was an ad for Alzheimers help.
The timing was priceless.
No, I'm not suggesting you have alzheimers, just thought the timing was something for Jay Leno.
