This should not happend. There are two potential 
causes for this problem:
- use of javascript and generated links (or 
javascript: URLs)
- use of flash files WITH embedded links

Check the page sources - I think your problem might be 
javascripting

Another potential problem might be a bogus parameter 
(example: mirror depth set to 1 or 2, or experts 
options concerning link rewriting changed (note: 
generally changing "experts only" options if a BAD 
idea))
