delaybody -- no response

I have been using delaybody, but seem to have run into a problem where 
leafnode keeps trying to get the body for a few messages but can't (for 
whatever reason).

is it safe to just go into the firefox file in interesting.groups and 
just delete out the lines?  This is where leafnode keeps track of which 
articles need bodies?
