For Modelling in Maya I need to move a vertex by in a sliding edge= Select vertex> arrow move key + hold C> drag middle mouse move on that beside edge. But clicking my middle mouse once keep on zooming by itself in Maya only. I remember I do not have this problem from before with my old mouse. I think only my new mouse have this problem that I cannot middle mouse click only without zooming.

Please, help my mouse settings not to zoom when I am trying to middle mouse click only. I am using Maya with mac only. Do I need to try to buy a new mouse again.
