In my experience, changing screens is not a problem for windows
created directly by X11 (i.e., xterm or rxvt windows), but it is
a problem for some daughter windows created by programs launched
from an X11 terminal. Some daughter windows map to specific locations
and sizes on the screen (e.g., in tcl programs we write), and changing
from a big screen or dual monitor environment to a single small screen
can result in the daughter windows being mapped to locations outside
the existing screen.
For example, if I launch pymol (a program for displaying molecular
structures), it creates a "terminal" window and another window used
to draw and manipulate a structure. If I change my monitor environment,
the "terminal" window (and all X11 xterm and rxvt windows) work fine,
but the daughter window created by pymol functions poorly --either not
allowing rotation, zooming, etc., or functioning very slowly. If I
reset the monitor to the original environment (i.e., put the powerbook
to sleep, plug in my external monitor, and wake the computer back up),
everything works fine again.
I presume this is something that cannot be easily fixed, as some of
our programs are written in languages that specifically map daughter windows
to certain screen positions and sizes (e.g., tcl), and I'm not sure that
these programs automatically adjust to changes in screen dimensions, etc....
but then again, I'm not a programmer......

10.2 wasn't aware of screen changes without re-starting X11.
10.3 is aware when you add or remove external displays.
