Dont think you can turn off the tool tips.
Thanks for the help.
The boxes contain clip info which I don't need.
I suspect that it may be windows 10 that is causing the issue. I have the hover box in window 10 unchecked but that does not fix the problem.
I own Pro, that might deal with it, but they won't let me install it on any of my new computers. :-(
PPr. has a preference to turn off tooltips but that does not include clip info on the timeline.
