This has been on going. Nothing that suddenly popped up. From time to time when I click on a symbol so it can load the chart, the data in the watchlist zeros out and repopulates. I'm displaying the following - last, change, ch% and volume - these blank out and reload when I interact with it, by clicking on a ticker. Pressure and Trend that is displayed seems to be remembered.
The recovery of repopulating the data is fairly quick. All the windows I got open, I'd probably want to just quit and repopulate also Maybe I just got too much going on?
