Rack Pinion Mate Glitch

Using the Rack Pinion mate and it seems to have a glitch. The rack runs smoothly but the pinion is erratic and gets out of time in relation to the rack.

I did a forum search and it seems like there's a bug but couldn't find anywhere that it was said to be fixed.

Also there's link to a Gabijack blog post on this bug but the link is dead.

I'm running 2010 Standard, SP0

Has this bug been fixed, and if so at which release/ service patch?

Another question would be is there a workaround?
