Premiere freezes double click audio on timeline to see in source window.

Hi,

Many times when I double click an audio file on the Timeline then Premiere Pro freezes. I'm trying to see the audio in the Source window to do more fine tuning.

I have been using Premiere Pro to do the same processes forever. Or at least since 2014 when I started using Premiere Pro. And many years before that in FCP 7.

Premiere is 12.1 (build 10)

The Mac is fairly stacked.

Mac Pro (Late 2013)

3.5 GHz 6-Core Intel Xeon E5

32 GB 1866 MHz DDR3

AMD FirePro D500 3072 MB

I use two monitors for editing. The Viewer to see the feed out from the Timeline is the only Premiere panel on the second monitor.

There are no third party plugins.

Thanks.

Jason
