I'm on the latest update of Vegas Pro 19. I've been using the Ultimate S add-on for a bunch of years. My version is Ultimate S Pro version 4.2.1. It's extremely useful. As of today, however, I can't make it go away when I'm finished applying it. Its window stays open, blocking my Vegas Pro work area. I can't even resize its window anymore. Its window used to have an "X" for closing the window, but that's gone now. I've re-started Vegas, I've shut down and restarted Windows 10 (latest update), but nothing helps. Anyone else experiencing this?
Alternately... if this can't be fixed, I will uninstall Ultimate S, but I would miss some of its functionality, especially in handling Markers.
UPDATE: The responses posted by m3lquixd and John Dennis (below) are two methods for exactly what I was looking for, for deleting all markers in a project. Thanks very much, both of you..
