YouTube Editor Preview Doesn't Play

[kbgregory]

I uploaded a video on YouTube then selected "Editor" in Studio YouTube and made a cut. I put the cursor before the cut in preview mode and hit 'Play' on the video screen and it would not play. I had to switch to the Chrome browser, which worked fine.  Why would this happen?

Then in FireFox, I went to a previously uploaded video and in editor, I made a cut in preview, and the video played fine.
