Hi,
I'm kind of a newbie on the Maya platform, but I've made a few models before, and I've been introduced to rigging and IK. Now, I've made a simple cylindrical form (with a little top on it), and added a simple skeleton to it. What I'm trying to get is a pole that I can twist and turn in an animation, as if it were some kind of a snake. Now, I've added the skeleten, and smooth binded it, but when I try to manipulate the IK handle, I always get what you can see on image 1 (in the attachments). Now, I figured this is because the skin isn't weighted properly, so I went to the paint weight tool, but whenever I try to paint weight (as you can see on image 2), and I click somewhere else, and click back, the weight just reverted to its original value (as you can see on image 3). Now, it's been a while since I've worked with Maya, so it might be that I'm forgetting something obvious here, but I really don't know how I can fix this.

Thanks,
Arne
