here is a quick one for u Gurus?

We had a upgrade or somekind of installation here at work on our desktops and we had to reload Solid Works. One of the "things" that has changed is when I am out of all Assemblies my shortcut menu on the rih mouse button has changed . How do I change it back to my right hand mouse key shortcut  to making views for instance I can go to a front left right and my favorite the isometric view. I like to close my assembly and use the isometric shortcut and save my Asssembly in a isometric view. Please help.
