hello
I have made some freeky character and skinned a skeleton to it that the arms and legs are controlled by IKhandles. the problem is I am trying to paint the waight on the parts for example the feet and when I am done with painting the waight for each according to each joint, the default waight paint comes back. I even tried to hold them but it did not help. what is missing and how can I avoind having this problem again. to make it easier I have attached the file to this mail

thanks
