Same here. Just updated to 2.3.3, and am not happy with the result. Switched to default in Settings > Events, but I am also hoping this problem can be fixed soon!
I’m having a similar problem, which I did not have in 3.4. I’m running 3.4.1 now. I click Edit Image for a .jpeg in my library and my browser closes and recovers the page. I can’t edit the image, and I don’t understand why not . . .
