I ran 12 again all night last night, have not installed 13 yet. I had no issues whatever of any kind.
I did see in issue that has been present for some time, it was there in 2.3. It is not a functional issue since it does not interfere in any way with getting images. I don’t recall if I or anyone else has mentioned it.
Sometimes when something major has happened (focus, flip, etc.) the program closes the control panel, sequence window, and big status that I had displayed. Maybe this is a feature? It seems to be kinda random, however.
No big deal, a rather low priority item, but figured I would mention it.
