Well, it seems the next SR-3 for Poser 8 is coming SOON.

Sooo, maybe , hopefully this problem can be fixed before it is issued.

Here's the problem:
Poser 8 with SR-1 installed runs fine on my machine.

But when I install SR-2 or SR-2.1, this happens:
I load a figure and start the joint editor to work on the rigging.
But when I select a joint and try to grab a MAT-sphere to move it around, it just "zooms into space", leaving a broken joint.
(Which the "undo" function can't fix, btw)

I think I'm not the only one having this problem, but I suspect a lot of people don't notice this problem simply because they don't use the joint editor.

So may I ask that you do a quick joint editor test to check if it works properly on your machine ?
(With SR-2 or SR2.1 installed, of course)
Just load a figure and try to grab a MAT-sphere.
If it (slowly) follows your cursor, everything's fine.
If it "jumps" as soon as you touch it, then there's a problem.

Maybe if this bug can be detected across several different machines SM has a better chance to fix it.
(Or actually "un-fix" it as the joint editor worked worked until SR-1)

Many thanks in advance !
