Screen cap below. This laser is at a community shop, many users, so I don’t know how it got to this state-
Lightburn has some sort of zombie window or panel partially off-screen, overlapping the top left hand corner as shown. I can’t select it. It’s on top whenever LB is on top, and then puts itself on top of LB. When un-fullscreening LB and moving LB around, it doesn’t follow. If I close LB or kill its process, it will disappear but come back when LB is rebooted.
I reloaded an old prefs.ini and it STILL doesn’t go away.
