I have been testing ArcGIS Pro 2.9.2 and all was going well until....I changed symbology.
Somehow I managed to get a floating colour palette and it didn't have a cross so i couldn't close the window. Activating the window and pressing escape would not get rid of it either. It was like it was pinned to one spot. The only way to get rid of it was to close all the sessions of ArcGIS Pro that i had open (i think there were 3 at the time). I'm not sure how i got it to show up (double clicking a colour when changing symbology maybe). I was working in a 3D scene at the time so maybe it had something to do with that too.
Has anyone else had the same issue. Can I report this as a bug to ESRI?
