Decided to start using TWS instead of Gateway. I use the i3 window manager and use i3lock to lock the screen but notice that when I use i3lock to lock the screen TWS no longer responds to API requests. Can this be real? I haven't tried this with Gateway but it would correspond with the high quality of IB's software otherwise. Does anyone else have a similar experience where TWS will stop responding to API requests if the UI isn't being drawn?
