Now Vegas Movie Studio Platinum 17 is running fine and so far without crashing.
However, it does happen from time to time that the cursor in the timeline stops working. It does not "run" during playback.
When that happens, I save my project and restart Movie Studio Platinum 17, after which everything is normal.

Is there anyone here who can come up with a proposal for a more permanent solution to that problem.

Sincerely
Hans-Jørgen Sindholt.
