Thanks, but I have to give up on 4.2 now, because in the last week, it has crashed (editor window disappeared) two or three times while I was editing epub files. I've gotten in the habit of hitting either F4 or F9 to save the file after each edit or after every couple of edits, due to crashing problems I had months ago, so I usually don't lose much every time it crashes, but it's still very annoying when the window I'm working in disappears suddenly with no warning.
I have 3.48 installed now (which hasn't ever crashed at all that I can remember), and I'll just wait until more bugs have been fixed before I try it again. In 3.48, editing takes zero seconds for the rendering to be complete, and the text in the File Viewer window doesn't move at all after each edit. I prefer to use the no annoyances-no distractions-no crashes version of Calibre.
