Yes, I will try and find those patches for 5, I do not have a free 
machine that exhibits the problem, but, I do have my disk cloned so a 
quick test of a patch should be simple and risk free over a weekend when 
I have time to mess around.

If anyone has that link handy, please post. (for the patch)
