Hmm... if I answer that, do I still owe you my video card? :-) (Wouldn't 
do you any good on a 21", it's a "model one" XClaim GA 2Mb, but I guess 
you could have a 15" "third" monitor...)

Actually, I'm right-handed. The "extra monitor on the left" habit came 
from that old Radius, which threw out a lot of interference on it's left 
side, so when it was on the right, the SE's monitor was "snowy". Doing 
this does require that I set the left monitor a few pixels "lower" than 
the right one (with the menubar) so I don't "overshoot" the Apple menu in 
the upper-left corner - I need a little "lip" up there to catch the mouse.

Try moving your menubar to the monochrome monitor, leaving the color one 
at 256, and run one of those programs; if they've followed "the rules", 
it'll run on the color monitor _even_though_ it's no longer the "primary" 
one. My guess is you'll hit about 50% that work fine, and 50% that say 
"you have to have at least 256 colors" and flat refuse to run.

Ah! I've got a "freebie" magazine-bound CD of that somewhere in this mess 
that I've never tried...

You're welcome... And in payment to myself for typing all that, I think 
I'm going to take Thursday off from both programming _and_ answering 
email! :-)

(The fact that I'll be off stuffing myself with Thanskgiving-type 
foodstuffs is irrelevant, of course...)
