Driver Side window vs. side view mirror?

So on the driver side of the 66 ddart, if I want to push the little triangle vent window open, it hits the side view mirror after about 1 inch. Hummm,,, is that how the car was designed?
Do I have to move the mirror out of the way, then open the window, then readjust the mirror?
I am using the original mirror....i think.
Anyone else testify to this?
