As of about a week ago, I'm having some problems with my Mb-D10 on my D700. When the grip is attached I'm trying to move my focus point using the multi-selector on the grip. The focus point simply won't move at all. It moves fine using the one on the d700 body, and I'm 100% certain the focus point "lock" isn't in use. I've recharged the batteries and removed the grip and put it back on several times. Any suggestions what may be the problem? I could be wrong but I don't think there is a camera setting to toggle it on/off. Thanks.
