i posted this yesterday, received response, but thread has been deleted.
I'm using the Lighting Effect filter in PS, and it allows me (sometimes) to add a lighting effect and allows me (sometimes) to edit same, but 95% of time I have to close out and try again, and again, and again.
So it does not "freeze" PS, but when i resize the light/use sliders/etc, nothing happens/changes not applied. It is not "if" it will happen, it is "when".
Note. Legacy feature no longer available. Below are my specs:
