More efficent checking of multiple objects

[David Burgun]

Hi,

You could also put the mouse up handler in the group and change it 
slightly as so:

on mouseUp
put theArray[the name of the target] into myValue
put DoMouseUpInRect(the name of the target,myValue) into myResult
end mouseUp

All the Best
Dave
