Hello Arne,
YOU ARE A GENIUS!!! THANK YOU THANK YOU!!!
You were absolutely right, I went to the project setup, and for some strange reason it was something like over 8+ hours? The track is only about 5 minutes long, so I don’t know how that happened, but in any event changing the project duration to a more reasonable length (I put 10 minutes) solved the problem, and now my scroll bar is normal again!
This should be a sticky, in case anyone has this same issue, as I’ve seen it mentioned a few times randomly, but with no solutions. Once again, thank you so much for your help!!!
