Old model's Iso view is Front?

Hello;

     I pulled up an old model, that we're going to be using, & the Iso view is shown as a front view. What's a little strange

about this is that there is a front view & all the others. I even restored the front view with the view orientation, but when I hit the isometric, diametric, or trimetric, they all appear as the front view. I would think once I set the front etc., that the Iso view would be automatic, which it's not, it goes to a front view. Has anyone ever run into this or have any ideas?  

Thanks in advance for any input,
