Well if you want to drive yourself nuts, check your site in IE 5.5 , Netscape 6.0 and Netscape 4.7X. Netscape 6.0 has some major bugs. No wonder the report I read said Netscape is losing ground, anfd people are uisng IE. I switched after 2-3 years of using netscape..
One bug I just noticed is the first line of a post is in default text, the rest is in the font chosen..
Aghhhhhhhhhhhhhhhhh
