Hello Vegas Community.

A while ago, I created a post with bugs found in the latest v23.

I am not sure if this has been reported already, but I found out why sometimes the cursor doesn't move anymore, or tracks auto-collapse. Reference post: https://www.vegascreativesoftware.info/us/forum/bugs-after-latest-version-color-grading-again-auto-collapse-more--150742/

The best way to fix this is to remove any track motion Keyframe, or to set it to default (aka - nothing), and to add it at the very end of the project, whenever you need to render.

In the screenshot above, I have it set as I need it, hence the project gets buggy:
- The cursor doesn't move when I press play.
- The tracks on the left, as you can see, are all collapsed/minimized.

Resetting the keyframe (in my case, it's only one at the very beginning of the track) fixes the issue.

I hope this can help the DEVs.
