Hi Damien!
yes, I do have that button. Thank you, I had forgotten about that feature.
So, I clicked on that button and the screen went smaller (obviously) and then I stretched the screen to fit my monitor. Did my adjustments (which I learned in your AMAZING raw class - thank you for that!) and opened the image in PS. Went back to another ACR edit 2x now and the screen is back to how it should be. What did I really do? I have no idea, but try that!
Thanks!
J
