I have seen that combo run - do you get screen-flicker on your intraday charts? I seem to recall seeing that problem with that setup. As for 2000i, I have seen it run fine on XP, though that was running EOD scans. The only time I've seen it getting realtime data, I saw the charts flickering.
the flicker can be an issue yes, esp w/ futures. the 'fix' is to configure the symbol as an index or stock. i don't recall the specifics, but it was well known among users, and discussed on the esignal / tradestation forum
The 1st thing to ask would be, why are you so "stuck" on ts2ki? Why not go to their new internet platform which has data on demand, tradestation.com? What's the specific reason?
