rigging hand

Finally managed to get the feet behaving like they should, using the set driven keys window and moved onto the hands. IK handle connects the shoulder joint to the wrist, but on second glance of the tutorials example I notice he has an extra joint in the hand. Not sure if this is going to be a major issue, but decided to use the "insert joint tool" (animation menu, skeleton, insert joint tool).
Seemed to have done the trick, apart from the hand moves in a really irregular fashion when you use the move tool - not good! Originally i thought it could be down to the local rotation axis not all pointing in the same direction, so checked that using the display menu. What i think has gone wrong is the placement of the IK handle. Because I've added a new wrist bone, the position of the IK handles destination has changed. So, to rectify this i'll delete it and re-attach in the correct position.
