Hi Sorry for the late reply,
Nat -- I was not holding the space bar, and in fact the skipping to the end happens when I click the pause button as well.
As for the auto-repeat, I'm not sure how to change those settings, but as far as I know I have not altered them.
Borate -- your uncorrupted fixed version works. No issues pausing with space bar.
Do you know why that would have happened?
