I always do this with only one search tab running. If you do it with more than one tab running the order might change on next opening. Just a thought any way ...It might help...
otherwise, deleting your preference folder might cure the problem, but if you do that your save options will return to default and you might loose some incomplete downloads.
Help for seleting prefs. that is in this thread
