how to know 2 monitors are in use?

[Nicolas Cueto]

Thank you, Paul.

Using "screenrects" as Paul suggested, here, for future reference, is a
script snippet that places a stack on the right monitor:

 put the screenrects into tScrRects
 if the environment is "development" and the number of lines in tScrRects >
1 then
      -- CENTRE THE STACK ON THE RIGHT MONITOR
      put line 2 of tScrRects into tRMon -- right monitor rect
      put ((item 3 of tRMon - item 1 of tRMon) / 2 + item 1 of tRMon) &
comma & \
            ((item 4 of tRMon - item 2 of tRMon) / 2) into tRect
      set the loc of this stack to tRect
   else
      -- CENTRE THE STACK ON TE LEFT MONITOR
      set the loc of this stack to the screenloc
   end if
