Lightroom has no scratch file or memory controls. I usually start Lightroom and let it do whatever it does for a few minutes before using it (like just now ...

You might check the settings you've made for what kinds of previews it makes automatically and how long it keeps them. G On Oct 7, 2007, at 11:07 AM, P. J.
