search error? nm

[imported_Mike]

while in fs/ft forum, i typed in a search word and was presented with threads that match my "key" word, i can click on any of the threads, but when i push the back button to go back to the list of threads that match my "key" word i get a page has expired error. any suggestions as to why this is happening?

editnm, must have been a fluke, seems fine now.
