Hello all. The past couple of days, my TWS has been behaving funny. First I noticed that the data (prices etc.) for stocks were not updating, and will sometimes just show ???, and my excel sheet using RTD excel not working/updating either. When I then try to close down (exit) TWS, it just hangs at the message "Shutdown API..." (picture attached) and I have to close it down via task manager. I have uninstalled and reinstalled various versions of TWS (latest, stable, 32-bit and 64-bit) and API 975.01, but still having the issue. Don't know what else to do now, I am completely stunned! The only other thing to add is that I noticed it about (not saying it is necessarily related) when I installed an excel add-in (Stock-Connector) from microsoft app store (to stream stock prices into my excel sheet, for when I can't get certain prices from TWS into excel, happens sometimes). However, I have disabled this add-in, and even restored my PC to before the add-in installation, but still getting the issue! I just seem to spend more time sorting out issues with programs, websites not connecting, PC issues etc. than actual trading!
