Hi Everyone,  
I have a chronic problem with my waveforms disappearing.  When they disappear they usually display in a single line across the middle of the clip.  To get the waveform display back I have to highlight the clip/clips and bounce them down to get the graphics back. Does this have something to do with my picture catch being too full?  If so, where is the picture catch located. I'm looking on my "C" drive, but for some reason I'm not finding it.  Thanks for your response.
 

Hi. The Picture Cache is located by default in C:\Cakewalk Projects\Picture Cache.
You could also try to right click on the clip, choose associated files and click recompute picture(s).
All the best.

Thank you.

You can also recalculate waveforms by right clicking and choosing the bottom item in the list. Recalculate Is on the dialogue that opens.
