I was actually thinking the other day about how the bit of code which does
this might be wrong. :S

I suspect the problem is that when you have the secondary to the left of the
primary, the windows on that monitor have negative coordinates.  The code
which constrains windows to lie on the display does the wrong thing in that
situation, so they can appear offscreen.  I'm not sure if that's the only
problem in that configuration, though.... but the patch you linked to should
be making everything fine once the window is visible, so maybe it really is
only a window placement issue.

If possible, make the display on the left the primary and see if things get
better :)

I don't think this is a regression against the 6.9 server.

I agree it is clearly wrong, though.  Windows should be managing the location
of this dialog for us, though and should know enough not do that (X programs
think that the display is one big screen, and so can't know not to put dialogs
on the crack between screens)

-multiwindow means "hide the root window and use the internal window manager
to integrate X windows with native windows"

-multiplemonitors means "I want one big X screen for this display to span all
my monitors" and is on by default in -multiwindow mode

If you want -multiwindow mode, but only on 1 screen, something like "XWin
-screen 0 @1 -multiwindow" should work.
