Problem with camera perspecitve

[daiku]

At the start of my script, I save a copy of the current camera, then assign a new one with different parameters. At the end of the script, I restore the saved camera. But if I turn off perspective for the new camera, the perspective does not revert back when I restore the saved camera. I boiled down my script to the bare bones to illustrate the problem. If you change the false in line 20 to true, or to old_cam.perspective?, it works fine. Anyone know what's going on here? CB.
