I've had Blender 2.75 for a few days now and I've run into this problem. I'm trying to make my "character"lip sync however I can't select multiple vertices, I've tried b and c keys yet nothing but a few vertexes are being selected, which I didn't need like ones on the hair. I imported this character from wow model viewer, I watched a tutorial on it and everything looked like it was going fine he could manipulate and move them just fine. Also the vertices aren't "linked" together if I move one it will create a hole and the other vertices around them will simply stay in their original state. You can see how this is a problem. I tried to make mouth movements using bones but that was very time consuming so I eventually gave up :/ Help meh D:
