I have come across something really odd. I had a bug which in Opera 7 caused the whole page content to be in the right of two columns, each a quarter page wide. I had named my column classes "col1" and "col2" in a two-column layout. What I have eventually found, and have repeated several times, is that renaming "col2" as "rightcol" and changing the DIV class to that as well makes a dramatic difference - lo, I get two columns the right width. Still working on putting them side by side but thats something else. I checked carefully, "col1" does not appear anywhere else in the html document so it isnt due to its effect somewhere else. I wonder if the character string "col2" has some secret meaning in Opera?
