Hi Dennis,
It's been a while. Just wanted to drop a note and say that ever since I moved to 17.0.3.0, things got much better with the UI lock-ups. However, I still see them, especially when I move focus to another window and then come back to SE. It will stall for about 5 seconds (enough for Windows to think the app is unresponsive) and then it will work again. Better than the multi-second stalls from before, but still happening. Not as annoying as before, but still annoying.
Let me know if there's anything I can do to help you diagnose the remaining issues.
Thanks,
Bruno.
