Hi, I don't know what I did or pressed! but when I open LR Classic on Mac computer I only get half of the programn on the screen with all 3 traffic lights on menu bar. When I click on the green light to expand to full screen (it shows 2 arrows on light) I have lost the menu bar on the top page but can access it by hovering over the top of page although the amber light is now grey so I can't minimise the page. I have the screen mode on normal. help required please.
Thanks for the reply which I acknowledged earlier but mailbox was full! The F keyboard didn't work, what did work was when I updated the Mac under settings and once re-booted the LR screen was as normal.
