It feels as if it is trying to prevent clashes as I pull. This makes it much harder to shape the protein how I want. I remember trying to pull a loop to a different location and all it did was sort of twitch and wriggle in place. I ended up having to pull at a somewhat oblique angle away from the protein and then pull it back in to get it where I wanted. When I am using the pull tool, I don't care about clashes.
Also, why is the spam filter so picky? This is not spam. I gave the captcha code. Why didn't it ask for the captcha code in the first place? Is this because of my high activity over a short period of time? This spam filter isn't very good.
