I've been using NT and IBKR for months. With TWS (10.33). It works pretty good. Today for some reason every time I have an order filled TWS opens up an API window. I've never seen this window before in thousands of trades but today it will not stop popping up and I cannot find the setting for it to go away.
Do you know if anything inside NT could make this thing start appearing? I did not update IBKR, I've been using the version recommended by NT.
