I don't think it's any of the above. I have done everything suggested in this thread, to no avail. I even tried uninstalling the latest version of #2 - going back as far as #1 - no appreciable difference. I checked all drivers, blah blah. I've been working with PCs forever (since pre-DOS) so I know my way around and rarely get defeated by a system issue. I HATE that I can't figure this out. Everything else runs brilliantly on the laptop - multitasking with huge Photoshop files, word processors etc. without a hint of slowness. I can only conclude it's Calibre, and apparently Calibre only, not liking SOMETHING about my system.
This following bit should probably be in a separate thread, and I will probably duplicate it. At this stage I feel darned near suicidal, LOL. Not that suicide is a laughing matter, of course. Calibre is just behaving extremely strangely. My usual workflow is:
Enter the data I want, either from the booklist of the "info" screen. This comprises nothing but Series and Country of the Author. I also check the publication date for the original release date. Anal huh??
Next, run Epub modify, to insert a jacket into the book.
Run Quality Check to swap Author FN/LN
Delete epub original files.
I have been following that same pattern for years!
So, today, I move -- painstakingly and VERY, VERY slowly, a few at a time so I don't rip what remains of my hair out -- all books missing tags in the booklist to a temporary library. (Why were they missing in the first place, I ask?? I figured it was just some aberration/my fault/whatever.) Then I painstakingly and VERY, VERY slowly correct the booklist data for all the books that had mysteriously lost their tags and comments and move them back to my main library. About 500 books -- it took me all day because of aforementioned speed issues. Interestingly, things did NOT appreciably speed up as the number of books in the temp library dwindled. The last move of about 25 books took as long as the first one. Possibly because the holdup is at the other end, in the main library.
11:30 tonight I finished and switched to the main library only to find that every single book I modified today had no tags, no comments. GEEZ. I truly could cry. In fact I think I will. I couldn't duplicate this on my PC. I give up.
