Auto-scroll during recording will occasionally stop
Occasionally whilst recording in a multitrack session, auto-scrolling stops (the recording playhead moves offscreen beyond the right boundary) requiring manually scrolling of the viewport to keep track of the waveform.
This is very annoying and I've experienced this issue on multiple Audition versions and operating systems over the years.

I'm having the same problem!
I have found that this happens mostly when zoomed in multitrack. If you use the (+) and (-) keys to zoom instead of the mouse scroll, the playhead continues to move. Literally if you do not touch the mouse and zoom using the keys instead, the playhead moves no problem. You can usually use the mouse afterwards.
