On p.75 of the P3 manual, they say to select the 'rotate' tool, select the arm and drag down to lower the arm...well, when I do that, only the elbow joint moves, not the arm itself. I've tried selecting both forearm and upper arm and they 'select' just fine, they just cannot be raised or lowered, only rotated at the elbow. This is such a basic function of the program, yet it's not working. Problem # 2 is that when I select figure 2 to work on, figure 1 continues to move...? It seems to select a part at random, too--it doesn't move the part I've selected on figure 2. I reselect 2 and the same thing happens as soon as I try to alter him--figure 1 begins contorting. I suspect that in working my way through the tutorial, I must have altered some basic setting accidentally....???
