Importing a Snapshot from a window off screen

[Ray]

Paul - once again thanks for this insight.  I'd thought I'd let you know 
the following script which groups everything on the card, gets a 
snapshot /of the group/, and then ungroups everything, is working well.

on importGroupSnapshot snapName,myRect
    repeat with C=1 to number of controls
       set the selected of control C to true
    end repeat
    group
    import snapshot from rectangle myRect of last grp
    set the name of last img to snapName
    select last group
    ungroup
    select empty
    choose the browse tool
end importGroupSnapshot

Thanks again!
