Also, I have a class for main_heading that seems to be totally ignored. Other
class definitions are shown correctly.
When I open the html document in either Netscape or MSE, everything looks as
it should including the background and main_heading.
When it stopped working, I had been looking in the Options sub menu for
something else -- I may have accidentally changed something, but can't tell
what.
I did reinstall HS, but that didn't solve the problem.
