Guestbook header does not keep settings

[bruce]

Saturday night I set up a Guestbook for "A Meddle of Wizards." The header setup page was difficult to set font size and font face, but I finally managed. Everything looked good in 4 different browsers on a PC and a Mac.

Today when I showed the Guestbook to a friend, the font size and face had changed in a portion of the text (titles only), and one of the titles was no longer centered. I later discovered that the Guestbook header looked fine in only Firefox on a PC. All other browsers displayed the above problems.

Furthermore, when I attempted to correct the problems in the settings portion, the setting screen appeared to be correct and the Live Guestbook appeared to be correct as well, but only in Firefox. The setting screen appeared correct with Internet Explorer but the Live Guestbook was not. A couple minutes later, the font face and center alignment had changed in the settings area without my changing anything!

Also, I can no longer make any font changes nor can I decrease indent using any browser. Each press of the decrease indent causes an additional indent!

This has been very frustrating. Can you please help?
