Then, I do not think that your XINERAMA extension is working, and you are
in the same position that Joe. And it could also be that the Mac window
manager is enforcing this.

If your XINERAMA extension is working properly, then you should be able to
do something like:

WINDOW, XPOS=1000

and have the window straddle the monitors.

When you say "Windows", do you mean IDL windows, or any window?

What happens if you open a Finder window, for example, and try to drag it
to the other monitor?

This is expected. The idea here is that this information is useful for a
MM-aware IDL application that may wish to lay out several windows across
the desktop and avoid straddling the boundary between monitors. If all
the info the app has is something like "3200x1200", it cannot tell exactly
what part of the desktop is on which monitor.

The IDLSysMonitiorInfo object also has a method called IsExtendedDesktop.
If this in non-zero, then IDL thinks that you are running a desktop that
spans the monitors, which implies that XINERAMA is advertised as working.
