Quote from OldTrader:
I don't use Norton anymore...but when I did, it did not conflict with TWS. I'm inclined to think that whatever the problem was had to do with some other factor.

Well, they keep changing the stuff, don't they? Perhaps your earlier iteration of Norton interacted differently with your earlier iteration of TWS. Or, yes, perhaps another factor was at work. A software expert I am not I do know, however, that I was only able to acheive "non-twitchy" TWS performance once I had uninstalled TWS, uninstalled Norton (SystemWorks), reinstalled TWS, then reinstalled Norton, in that order. To the best of my knowledge, all other variables remained constant -- although perhaps it was some root directory thingy or other bit of computer code arcana that somehow corrected itself. I don't know.
