OK, there has to be a really easy answer to this. When I open PS5 on Mac, I have a large, gray area that will receive a dragged file and open it. I have been doing this for so long, I have forgotten how I set PS to have this happen.
I just updated to a newer PowerBook, installed PS5, and I can't find the preference to have it open to the gray frame. Don't make fun of an old person, just help him! 8-) Thanks
