if you are talking about DisplayPerformancePreference:
Member of InDesign
Application's default display performance settings
then nothing was changed - CS2 work the same way like CS3 and CS4
but if you are talking about EnableRedraw
Property EnableRedraw As Boolean
Member of InDesign.ScriptPreference
If true, enables redraw during script execution
then it was introduced in CS3
Sorry I was not quite clear. I mean the view that shows the page like it will be printed, without frame edges, bleed, ....
The command for desactivating the Preview mode in CS3/CS4 is:
Set the screen mode to preview off
But I can't find the equivalent for this command in CS2, although the Preview mode exists in the user interface.
I'm sorry Peter, but I'm not AppleScript man
