I had the black screen issue after installing vers 22. There are multiple fixes listed here that temporarily might help that. But I've also recently starting having total freeze ups where they only way out is to force the application down and lose work.
I would suggest right now everyone goes back to 21 that are having any troubles. I'm going to this afternoon. Lost too much work and time already. I hate to, as that single feature upgrade of sky replacement alone already has me hooked.
