Re: [jed-users] Odd exit behavior

[Tom Culliton <tom.culliton@xxxxxxxxx>]

@Gunter - The key seems to have been exiting from the find_file dialog in
the mini-buffer before something else autoloads those. Not sure if there
are other paths. Exiting from the *scratch* buffer or the mini-buffer while
doing a search doesn't seem to trigger it.
