CS6 locks up when I open a RAW file. Doesn't matter how I open the file. Other files open fine. This just started happening and I haven't changed anything on my PC. I'm running Windows 7 and have plenty of RAM.
Have you installed all the updates to Photoshop and ACR?
What kind of CPU are you using?
I've installed all the Adobe And ACR updates. My CPU is Intel i-7-2600 @ 3.40 GHz. 16 GB RAM.
Does it lock up whether you open from Bridge or PS?
I ran updates again. Not sure I did the ACR updates before. It seems to have fixed the problem. Thanks for all the help.
