Jerry,
I would really like to be one of your testers too. I have used QT since '99, including some time with Ameritrade. I've been staying out of active trading since '08 but am back in now and have started up with the old QT version 3.9.8
FWIW, I have been in IT for 33 years so I might be able to contribute something along related issues.
My wife is a fairly active trader and still uses QT with a feed from an Ameritrade account that we have just for getting real time quotes. We're fans.
