I have no malware and no add-on utilities that would cause the (few) problems I have when using Calibre. My configuration of Windows is not much different from the original installation, and anything I've changed would not affect the performance of Calibre.

When I create EPUB files, I have no problems with Calibre. You have assumed that I make basic EPUB errors, but you are wrong. I'm a perfectionist and have done a lot of research on CSS coding and how to create EPUB files. The EPUB files I've been working on recently were not created by me. I am fixing several things in many EPUB files that were created by others, mainly publishers. As you probably know, publishers make errors all the time in their EPUB files. One example is that image files and HTML pages for the images are not coded correctly, so this is not something I've done wrong. I am taking the time to fix them (working in Calibre for up to 16 hours every day). Calibre fixes those problems sometimes, and sometimes, it doesn't. I have only pointed out a couple of things that Calibre doesn't fix.

I realize that EPUB coding is similar to HTML coding and that there are differences. Being a technical person in computer use for 33 years, running a 4-line 6-computer BBS for more than 7 years, building computers for 26 years, having a 4-computer home network, and having two very popular web sites in the 90s and early 00s, I'm very familiar with how to do both.

One thing I plan to do in the near future is to replace my power supply, motherboard, and hard drive. (I added an addl 8GB RAM chip, but it made no difference.) There's a possibility that a piece of hardware in this computer is in the beginning stage of failing and might be causing the "Calibre crashing" problems I've had recently, but I also have been a much heavier user of Calibre in the last four months or so than I used to be, so I really believe that's why I've noticed more problems than other "normal" users have.
