The controls on all PC programs for minimizing, closing and restoring the screen are missing in my Lightroom 5.7.1 program. This happened just yesterday but I don't know if I did something to cause it. I'm referring to the controls in the top right corner for all PC programs. X for shut down, "-" for minimize and the square box for a custom or medium size. They still exist in all other programs. I don't see anything different in Lightroom except this basic control. I have a PC running an Intel processer. I've been using Lightroom for years and I installed this version when it came out last fall. On the top left I still see the Lightroom controls such as File, Edit, Library, Photo, etc. The result is that I can only shut down Lightroom by going to File and then clicking on exit. How do I bring these controls back into view? This is only in Lightroom. If the cut and paste images works, these are the basic controls I'm looking for:
This is what I see in Lightroom
Press Shift+F once or twice.
