Hi all... I'm new here - hope this is the right place to post this question.
I am using Lightroom 3 on a Macbook Air. I have my catalog settings set to discard 1:1 previews after 30 days, but I seem to be losing them very quickly. For example - I am working on editing a batch of about 100 photos. I tell LR to generate 1:1 previews, which it does. When I close the app and come back to it later to work on the photos again, I see the "Loading" thingy every time I try to zoom in on a photo for editing. If I generate 1:1 previews again, this goes away.
Any idea what could be causing this?
Here are my catalog settings:
Thanks for any advice!
