Opinion Please -- R&P Focuser Problem

Hi,
I just received a Celestron 80mm f5 WA Eq refractor. I like the scope but
it seems to have a focuser problem. I noticed that when reversing focuser
direction, the image jumps about 20% of a FOV width at 32x. At first I
thought I was moving the mount, but on closer inspection in the light, I
can actually see the focuser tube "lift up" a bit when I back the tube out
after moving it in. This is my first refractor and first R&P focuser (my
Dob has a JMI Crayford), but I can't believe this is normal even in an
inexpensive scope like this. Opinions very much appreciated!

Thanks,
Al
