Thanks.
It's indeed hard to do anything with this without more details. Some
questions:
. Are the problems in java-mode and org-mode similar? It doesn't
sound like that, but I'm not sure.
. Do you have similar Emacs customizations on both systems where you
see this?
. Can you make this happen in "emacs -Q"?
Thanks.
