Does right clicking on the sheet bring up a menu when the "More Options" does a menu appear?
Another troubleshooting step that could be taken the next time it occurrs is disabling accelerated graphics.
To disable accelerated graphics:Help > Settings and Performance > un tick/check Enable accelerated graphics.
Hope this helps!
I've been experiencing this same issue on Tableau 2018.1.1 and colleagues have mentioned the same behavior.
Unfortunately, adjusting the "Enable Accelerated Graphics" did not resolve the issue.
It would be great to get a resolution on this as it forces the user to shut down and re-open the workbook.
I am going to do some additional research on the topic and see what I can find.
Did you ever find out what causes this? I am stuck on 10.4.0 and don't have the luxury of upgrading easily. If I want to upgrade I would need to have our IT department upgrade all of our Reader users first across our enterprise. I'm particularly interested in knowing if new versions fix this.
we never did figure out why it happened. Our Tech people think it might be one of the Windows 10 updates didn't load properly. The only way they finally fixed it was to re-image my machine - take everything off and put it back on. and it hasn't happened since (knock wood!). And I still have 10.4 as well....our Tech folks won't do updates more than about every 2 years
