Since version 78.10.0 with any action (selecting an email, viewing or downloading an application, even just when unfolding the program) at any time the program can hang, sometimes for 10 seconds, sometimes for a minute. I am not the only one with this problem on different computers (at least 4 PC's). It's just that 2 updates have already come out and this problem still persists... </blockquote> Run Windows in safe mode with networking and see if TB performance is better. Safe mode bypasses startup apps such as antivirus which often cause hangs. Exclude the TB profile folder from AV scanning, leaving the real-time scan in place.
