I checked the opening of the "trades" window half a dozen times before that post. Now after the midnight reset, IT DOES NOT FUCKING WORK.
Thats a pretty strange problem ... if you rename the jts directory to get rid of all your old stuff and create a new installation does it work then?
Gotta say, 886.5 worked just fine. LOL. Looks like they must have corrected a problem that was existing before. When I opened TWS, all the detached windows went to where I had them, on screen 4. Prior to this I was having to move them over there each time I opened TWS. No problem at all with the "trades" window. I think kiwi might be right...maybe you got a corrupted file. IB can tell you what to do on that. OldTrader
Why don't you give them a phone call? Select the technical section when prompted. They don't bite. I've never used chat. As an amateur, I would guess you may have a corrupted file, because no one else appears to have the issue. OldTrader
Chatting is one thing (which I rarely do) and clearly didn't help in this case. But, have you done a clean reinstall?
