bug when using a rig from a biped guide in 6+ (and 5.0)

[patoland]

Hi, I know that this bug has been commented in xsibase but I still
can't find a solution...
I put some pictures here (just to make it more clear...)

Problem is: in XSI 6 or 6.1 after doing a rig from a biped guide I
can't use Reset Actor (from the anime menu) or Reset All from the
Synaptic view because two strange things happens

in the first case I lost control of both biped.Left.Foot and
biped.Right.Foot controlers...

in the second something worst happened: the legs pops in the opposite
way...(I used to try this method since XSI 5.0 because of a previous
bug, but now I can't believe this behavior). I assume that I'm doing
something wrong, anyone has a solution?
