Enable dual displays on iBooks running 10.5 and 10.6

The iBook G4 (and various other iBooks) do not support "spanning" dual displays (I believe Apple calls this feature "extended desktop") with Leopard or Snow Leopard. Evidence of this is the missing Arrangement tab in the Display System Preferences panel.

The Tiger version of Spanning Screen Doctor does, indeed, work correctly on an iBook G4 running 10.5.4. After rebooting, the Arrangement tab will now appear in the Display pane.

Hopefully this saves some iBook users some time and effort in resolving this issue.

[robg adds: We covered this app many years ago, but I thought it was worth an update for both newer hardware and newer OS versions.]
