make manual lens adjustment and hit the constrain crop checkbox
sometimes nothing happens (not tick appears, grey borders remain)
Somtimes you can tick it and nothing happens.
Sometimes you can tick it nothing happens but then click off the photo and back on, and the box is unticked but the crop has been applied!
ie its flaky.
ANyone else seen this?
Yep. And sometimes I click it and the check mark doesn't appear and the crop box doesn't appear but in the history panel it says "constrain crop - yes".
And sometimes it works the other way round: when I check it nothing happens and when I uncheck it it works.
I guess you learn to live with it. Some days it's cranky, and some it's happy and works. Just like people .
and another thing. Lens correction and crop synced between 2 raw files produces different pixel dimensions = my HDR software to poo itself. so If I've done my lens corrections first, then decide to do an HDR I've got to create a virtual copy, process the uncorrected files, import into lightroom then reapply the corrections. OY!
I'm not experiencing this at all on my WIndows 7 system. What I do see and would like changed is an option that when you untick 'Constrain Crop' the image reverts back to NO crop. Right now I have to manually reset the crop using CTRL + ALT + R.
This has been reported as a bug several times. I suggest you add your name to the comments in this thread
