Default MEL ?
I guess this is a MEL problem. I'm not sure.
For some reason, today when I started Maya, my ortho cameras were all gone. It looks like their translation values changed. Somewhere in the area of 32000. Anyway, it was easy to bring them back to the center of the world but the problem happens everything I restart Maya.
My question is, How can I tell Maya to reset the UI to the default values?
