Did you also move the Previews folder (i.e. Lightroom Catalog Previews.lrdata) which sits next to the catalog?
This needs to sit next to the catalog. Otherwise LR will create new ones.
However, this would only affect old imports.
What is your OS and exact version of Lightroom?
Also check your Catalog Settings [Ctrl+Alt+, ]
Here on the 'File Handling' tab you can set a fixed size for Standard previews, or set it to Auto.
If you have a fixed size set and your screen is larger, then I believe Lr will need to make the preview bigger (Loading) every time you view it larger on screen.
So try changing options here-
This seems to have worked! Thank you.
I never used to keep that on "auto" and it seemed to work fine. I wonder if my graphics settings changed during the PC makeover. My buddy helping out with a few things may have changed a few things.
I take it back....I'm now working on a larger folder of images and it's still popping up the "loading" dialog when scrolling through. Its only for a second or so, but the photo isn't 100% sharp until the loading is done. Again, something that I never ran into in the past.
I did indeed move the preview folder.
Lightroom CC -- 2015.10 Release (should be the latest)
Windows 10 - 64 Bit
Intel Core i7-3770k
Hard drive setup (all local drives -- NOT external):
SSD 1 -- Contains OS and Lightroom program files
SSD 2 -- Contains Lightroom catalog (and previews)
HDD -- Contains photos (files) that are being worked on in Lightroom
The only difference from this new hard drive set up is that Lightroom itself, and the catalog, are on different SSDs. I've always worked with the photos on the HDD.
