A new discovery in SL2...for me anyway :-)
Did you know that you can preview course within SL2 w/o utilizing the Preview button?
Well, I didn't until I accidentally dropped a piece of lettuce (yes, I was eating my salad at my desk) on the "spacebar". Went to retrieve it an my course started to play. In my 2nd monitor I could see the timeline moving.
I then, hit the spacebar again and it stopped the course view.
To make sure my 'puter didn't just do that on it's own hoping I'd drop more salad, I hit the spacebar again to test and....voila!
I'm so glad I made this discovery, now I don't have to wait until the rendering process in Preview made.
Thank you for listening :-)
