Quote - I'd like to be able to put 4 buttons on the desktop (like memory dots) that switch IK on and off.

Xen--  You can do that already, if you're willing to use up 4 of your 9 pose dots... which I for one am willing to do given how much animating I do.  If you want the pose dot code, let me know and I'll post it.  I'd do it now but I'm not on my Poser PC.

FYI, my 9 pose dots are:

1 = zero figure
2 = zero expression
3 = eyes point at main camera focus prop
4 = [temporary spare]
5 = turn on arms IK
6 = turn off arms IK
7 = special legs zero pose which works better for IK
8 = turn on legs IK
9 = turn off legs IK

I'd love to have more dots, though...maybe Poser 8
