There is a file

Okay for those of you who care about this sort of thing:

This works to get the names of all open windows from the Process Viewer. It works in the script editor
tell application "System Events"
	get name of every window of every process
	return the result
end tell

but when I attempt this in LC I get an execution error:
on mouseUp
   put "tell application " & quote & "System Events" & quote & cr into tScript
   put tab & "get name of every window of every process" & cr after tScript
   put tab & "return the result" & cr after tscript
   put "end tell" after tscript
   do tscript as applescript
   put the result
end mouseUp

I had to add the LC app in accessibility the first time it ran, but afterwards I get execution error as the result.

I mean dying dog with 2 broken legs and a clowder of cats scratching it's eyes out slow. I've checked Applescript forums too. Apprently there is no damned good way to tell if a file is open on a Mac without using the API provided by the OS. Sometimes Apple takes my breath away. And not in a good way.
