Apologize for not posting at an earlier time for I am pretty busy these days. But I went back to fix the model and at the end I found that it was really a simple problem that I just wasn't too focused to solve. (Bad habit which I must eliminate:p) Pyrus was right. The right border of the palm was pushed inward. I did that for the sake of an early attempt to further tweak the hand but that was a fatal mistake. So I put it in polygon mode and saw the problem right there then pushed it back as "normal" as I can see it where it was and then it worked. Thanks for all the inputs and I will keep in mind of the methods provided for future reference.

(Hm, dates on board are weird.)
