(I wrote the original message)
But I am using a toy machine. I saw the Z-Order stuff in the online help
and was still under the impression that floating should work on the Mac I
have at work. Thanks, though.

A little further reading reveals that only
the "toy" machines (Macs and PCs) have Z-order
control.
Cheers,

The documentation of the FLOATING keyword is
pretty clear that this doesn't work on every
machine, but only on those that "provide Z-order
control". Since this code works on my machine
(Windows) and not on yours, I conclude
you must be using one of those fancier, more
expensive machines that does not have "Z-order
control", whatever that is.
Cheers,
David
P.S. Let's just say I don't think there is a
system variable that will tell us if we have
Z-order control or not. :-)
