YES.

And I havent found a solution to it. I also have not submitted a ticket because the problem is so inconsistant. I am working on a project right now that was shot with the same camera, same day, etc. All footage imported into the library. When I bring the first few clips into the timeline to edit all is fine and waves are visible. I edit those then bring the next clips down and no waves on those. ???

Someone said you have to wait until all thumbnails load before doing anything...I have tried that as well and sometimes they appear and sometimes not. So....I dont have an answer but wanted to let you know you are not alone. There are others that have this issue as well. ____________________________________

Thank you - as you say too intermittant to log as a bug, but reload did it for me - in a mad panic something usually works - refreshing - in and out of sound editor - visiting both ends of the project - I've seldom (if ever) been left stranded with no waveform and no I can't categorically state what worked and when. or even why
