Timeline goes blank; can't scrub playhead (Cp9)
Hi all...
I am running into a repeated issue where I will be working on a slide and the timeline goes blank and the playhead becomes unselectable:

I have to restart Cp if I want to continue.
And before we go there, I am now in the habit of emptying the cache every time I close. I've done it three times today and within 10-20min this happens again.
Brand new computer, Win10. Suppose I should upgrage to Cp2017?
