Thanks Ross for your comments.  My remarks are interspersed below.

This is not, in general,  correct, though for "xinerama-unaware"
window managers, it  is.

For a "xinerama-aware" window manager (like KDE-2.2.2 is supposed to
be) the WM is aware that the large desktop is made up of two or more
physical displays, and does "the right thing" w.r.t. window
maximisation &c.

Not an option for me. I need the "drag" feature for visual experiments
I'm doing.

Again, not an option.  I'm running just one card: the new AGP
dual head nVIDIA Ge-Force 4 Ti.  One port is DVI-I (digital) for
driving a digital flat panel.
