Sometimes I have part of the text running off the right side when I preview a post and can't read the whole thing with FF. There have been a few times when reading posts, part of the text is off the right side and I couldn't scroll to get it onscreen. I think those times I had enlarged things more than usual (CTRL +) to read more easily. Considering all the variables they're dealing with, different browsers and operating systems, I'm amazed there aren't more issues.
This is the last time I'm frogging this project for the last time.
