Almost every time I change the angle of a picture in LR, it freezes. I use a Mac and the likelihood of a program freezing on a Mac in general is slim. This happens ALL the time. (And I tend not to shoot perfectly straight - it's a definite flaw of mine. So I find myself needing to alter the angle pretty often.) Does anyone know how to fix that???
When you say "freezing", do you mean for a few seconds, or minutes, or you have to reboot the computer?
If it's a few seconds, try doing the angle rotation slider before you click "Enable Profile Corrections" and before clicking on "Remove Chromatic Aberration"
It freezes LR and I need to force quit and reload LR before I can do anything else. The computer itself doesn't need rebooting, though. Where do I click "Enable Profile Corrections" and "Remove Chromatic Aberration"? I'm using LR 4 if it matters.
If you're having to restart Lightroom, then perhaps you ought to try the following:
Close Lightroom, delete your preference file, then restart Lightroom. The location of the preference file is here:
