Note that you cannot call sprite(x).getaProp(y) (using square brackets calls
getaProp internally) unless the sprite has entries in the
scriptInstanceList. So, to avoid script errors, first check
sprite(x).scriptInstanceList.count, then check for the property. It can't
have the property if the scriptInstanceList is empty anyway. For example:
on mouseUp me
repeat with i = 1 to the lastChannel
if( sprite(i).scriptInstanceList.count ) then
if( not voidP( sprite(i)[ #myBuiltInCursor ] ) ) then
sprite(i).cursor = sprite(i).myBuiltInCursor
end if
end if
end repeat
end
