Yepper - a pain in the ascii for sure.
Just as an FYI - I've written a vb6 app that does most of what you're doing
but with a GUI. I've also got plans to do what you describe for solving the
updating of tickers.
If you're interested we could exchange some info and I'll go ahead and write
that and release the exe and the source code to the AB community. I recall
that you can't release the script as you wrote it for someone else But I'd
be glad to so that everyone can run their own and you won't have to keep
running it and maintaining your site.
I can send you some docs and a sample of the app so you can take a look at,
if you'd like. Just contact me off line if interested.
