Line tracing

[Ken Ray]

Richard,

It must be a bug in OS X. If you assign the value to a variable first, and
then get the count, you actually get the right number. For example, if you
select to documents in the Finder and do this:

tell application "Finder"
  get the number of items of the selection
end tell

...you get "0". But if you do this:

tell application "Finder"
  copy the selection to mySel
  get the number of items of mySel
end tell

... you get "2". Go figure...
