Please help as I'm stymied! My Mac PS CS5.5, vs. 12.1 is behaving strange when more than one photo is open. I don't like tabs, so I've turned that off in preferences. I need to have several photos open at once, and like to spread them over the desktop to see them all at the same time. When I click on one photo, the others are behaving erratically: some are changing to show the same photo I clicked on or part of it. It's as if each window is connected. How do I turn that off or otherwise fix the problem, so that I can view each individual photo and even make changes to it, without it effecting the other open photos?
I have already tried rebooting and deleting the settings file by booting PS while holding down the command, option, and shift buttons. And I checked for updates, but looks like I have the latest.
Thanks for your answer. I tried fixing the following, but it didn't fix the problem.
This is a brand new copy of Photoshop. Previous copies have worked fine on this computer. I just went to preferences/performance and changed the memory usage allowance up to 89%--think it was at 70%, and made an external drive with 1000GB extra space another scratch disk. Then re-launched PS. Problem is still there and happens even if I only have two photos open, plus no other software besides internet browser open.
The mac is a fairly new tower with 6gb ram. Not sure how to find out which video card I have, but I did purchase the upgrade.
You may run into problems with starving the computer if you ramp up memory usage too high. Don't know about a Mac but with a Windows machine it is recommended the computer gets at least 2 gigs. But 6 gigs of RAM should be OK unless your images are huge.
If you have the latest version of the OS with a Mac that is all you can do for latest drivers.
That's the answer! Thanks, I sincerely appreciate it. I just played around with the settings in my performance preferences. It looks like the answer is in which GPU setting I check. I can keep the "Enable OpenGL Drawing" checked, if I change the option to basic, instead of normal or advanced. This fixed the specific problem, but still lets me do the birdseye zoom that I love.
So, if I want more, then I need to look into getting a better video card?
Thank you very much. Cindy
Sure wish I'd found you and this forum before Adobe tech support had me on hold for over 2 hours, then disconnected me. ugh!
well, thank you again for saving the day. I'm seriously behind on a book writing deadline and working with photos is imperative to the process. Cindy
