This is a new thing that started today (first time using PD is about 4 weeks):

I drag a clip into the timeline. Normally the waveform shows but for whatever reason it doesn't now it doesn't and I don't know why. Saving the project, closing PD, restarting PD and reopening the project and problem solved. But drag in the next clip and it's the same problem.

Any clues why this is happening? And how to solve?
