[support] Comment body not appearing in forum topics

[Steve Hays]

I'm new to Drupal (using 6.2).  Individual forum topic pages show only  
comment titles and authors--not nested comment bodies.  I would like  
to have these pages follow the same general appearance as blog pages-- 
showing nested comments.  Have I done something to disable nested  
comments in forums?  Can I do something to activate it? [Permissions  
isn't the problem.  I've tried both options for the j-query folding  
checkbox in Forums >> Settings.

I'm embarrassed to ask something that is probably so obvious. But if  
someone can answer, I'd appreciate it.
