Apple

tell application "Finder"

activate

set Window1Name to name of window 1

display dialog Window1Name

end tell

So the part of your script with a fault is this part:

repeat with aWindow in every window

display dialog ">" & name of aWindow as string

end repeat

If you look carefully, you will realise that aWindow has not been defined as a window so the script will find all the items in every window in the finder.

2. If there is no window or your loop runs out of further windows, then you will need an error catcher in your script. Perhaps you could try this:

tell application "Finder"

open window 1 -- this avoids the problem that finder may not be the active application when you run the script

set Window1Name to name of window 1 -- This is not necessary, but you had it so I left it in. Your script does not use the result.

repeat with aWindow in every window

try

display dialog ">" & name of aWindow as string -- items in window 1

on error

display dialog "That's all folks!" --

exit repeat

end try

end repeat

end tell
