Okay, I enabled the debugger as requested, on trying to drag and drop, 
hitting C-g just cause the bell to sound, nothing happened and the delay 
wasn't interrupted. In fact, when the file was eventually opened, the 
debugger didn't even pick up and give me a backtrace.

Opening another .cfg file with C-x C-f also had a bit of the 
bell-not-debugger problem when hitting C-g, but it did eventually give 
me the following backtrace:

Debugger entered--Lisp error: (quit)
  locate-dominating-file("//Server2/chris/folder/file.cfg" 
".dir-locals.el")
  dir-locals-find-file("//Server2/chris/folder/file.cfg")
  hack-dir-local-variables()
  hack-local-variables()
  normal-mode(t)
  after-find-file(nil t)
  find-file-noselect-1(#<buffer buildout.cfg>

"//Server2/chris/folder/file.cfg" ((134283655 . 49251) 105972995))
  find-file-noselect("../buildout.cfg" nil nil t)
  find-file("../buildout.cfg" t)
  call-interactively(find-file nil nil)

cheers,

Chris - be warned, I know no lisp ;-)
