That's great. :-)  I encounter similar reactions when the "dominant eye"

eyes isn't too hard, so I don't think of either eye as being *the* dominant
one.

The brain is capable of amazing conscious overrides, but that's one I'd
be afraid to experiment with - I value my stereo vision too highly. :-)
