I had severe problems with NT, my computer kept crashing/freezing, I am a happy camper with Ensign. Keep at it, you are doing wonderfully well, the standard is very high, I am certain you will pull through.
Thanks, Callmate. After talking with a couple of better-informed people, it doesn't seem as though the problem is a lack of RAM or technical specs, but rather the platform itself. I like the Ninjatrader platform, and clearly a number of the group (including Mr Black, Pepe, Palinuro, bi9foot and Romanus) are successfuly using it. A number of streamlining suggestions and work-arounds have been made. I'll try those, and should they fail, will switch to TradeNavigator which I downloaded and configured a few weeks ago, and which seems an equally popular option (used by Spydertrader, Ezzy, Guavaman, ljyoung and others).
I've got two screens and (now discontinued) video cards. Tums has made some suggestions - including Matrox triple head2go (sp?) - for augmenting my screen capacity.
He has also given me some very helpful advice on the requisite technical specifications for a second system (execution-only), which I intend to purchase shortly. I think I'll also need to invest in a backup power system and 2nd ISP, just to cover all the bases.
I'm not the most tech savvy so all advice has been invaluable, and I am thankful to everyone who has made suggestions.
