Ok! I just googled the "lssave" thing and found out that it has to do with the same LaunchServices thing I was talking about a couple days ago. Coincidentally, I found an apple discussion link that once again pointed to that LaunchServices database rebuilder that I gave the link to. I will now try it out and report back with results (if any).

EDIT: Ok, tried it out, and no luck on clearing these "lssave" cs_invalid_page messages. I don't think it will help me out in any other way, but I'll report back if it does somehow.
