Just to clarify: that should read Fear the Worst by Linwood Barclay. Both the title and author name are messed up.

Sorry - yes, that is what it should read, and it's messing up both title and author.

What Operating System do you use?
What is the version of calibre that you use?

Try going to Preferences - Look and Feel and changing the interface font to something generic like Ariel and see if that helps.

I'm using Windows Vista
Calibre is version 7.52 (but it's done this through a few updates now - just not sure exactly when it started)

I tried changing the font to Ariel (and a couple other common ones) but it still messes the cover up. It leaves letters out, but it seems to really have trouble with "t" and "s" - very weird. I just tried it on the book: Sudden The Marshal of Lawless, by Oliver Strange and got:

Sdden The Marshal of Laless by Srange, Olier (and all of the small "s" have little devil tails on them like the "s" in the photo.)

Also there is a Generate Cover GUI Plugin you might want to try.

I had downloaded this earlier today and kept getting error messages when I tried to use it, but now, after restarting a few times changing the fonts - it appears to be working. It is even putting the correct title and author in, so if all else fails, I can play around with this and see what it can do. Before I wasn't able to get it to even open the cover options box but I can now. Hopefully, what ever is causing the other issue will get resolved at some point - as long as I have some what to generate a cover, I can get by.

Thanks for the responses!
