Fiddling in the Frustrating, Finnicky, Full Filepat Fog

[Ken Norris]

OK, so the button handler in my test stack works most of the time
(yesterday, the darned thing opened another stack folder which I'd been in
before, not the designated folder):

on mouseUp
  set the defaultFolder to "/Macintosh HD/Desktop/Doggies/"
  answer file empty with filter "JPEGs,*.jpg"
  put url ("binfile:" & it) into img 1 of grp 1
end mouseUp

,,,but then I decided to try the same sequence without the answer list in a
stack script in the stack I'm actually developing. It FAILS, i.e., does
nothing (no error, nothing) and the image I called never shows up (watch
linewraps):

on openStack
  set the defaultFolder to "/Macintosh
HD/Desktop/MyRev_Stacks/Keyboard_Images/"
  put URL ("binfile:/KybdUp2.JPG/") into img 1 of grp 1
end openStack

...I can't see wghat th edifferenc might be. I've tried a number of
combinations for th efilepath, but nothing works.

Foghorn anyone? Help please...
