Thanks for your suggestions. I'll see what I can find at the weekend on that website mentioned in my original query.

I have Netscape 4.7 on this machine and the site looks fine. He must be one of a very few people who run with non-standard font settings. I can reproduce the "fault" by upping the font size. I have received two previous complaints (just two) about other sites I have written. I have explained to them how to set default font sizes.
Does that make sense to you?
