AudioSnap not 'active'
I run X1 Studio on PC Win 7; I have a project containing an audio clip (WAVE file) on one track. I am changing the project tempo and would like to get the audio clip to follow the new tempo -> so I select the clip, open the AudioSnap window, but nothing can be clicked within the AudioSnap window. Tempo, Timing, Filter, Nothing. It looks as if the elements within the window are 'inactive' even though they are visible / present. The Enable/Disable does not respond, either.
The only part that can be clicked and responds is the 'AudioSnap Options' window in the top right corner.
Probably very simple - but it drives me nuts not to be able to figure it out. The Manual doesn't give any tips or help for this type of issue.
What am I doing wrong, please?
