I'll start out by saying I don't know if this is a firefox issue or not, don't have IE installed so can't verify.  I make heavy use of the search function before posting and the biggest annoyance is, after the search, if it wasn't something I was looking for, I can hit back and get the error of " post function...yada " can't remember exactly.....go to another topic....hit back again and nothing happens.  Just a pain to have to type in the seach function and look again.  Is this a limitation of the software or firefox, ie.....etc
