Running two MainType windows

I often like to compare two fonts, usually to see how the one I’m working on differs
from some other font. I would like to:

a) open MainType twice to get two windows. I’m using Windows XP and
I don’t seem to be able to do that. Is it possible?

OR

b) open the more than one Characters area, Zoom area etc for different fonts. There would
be one Fonts window to make selections and open other window containing Characters, Zoom etc
