slowdown and disappearing menu in emacs 21.2

[David Novogrodsky]

After I added JDE to my emacs instalation ( emacs 21.2 running on Mac
OS X) I noticed a sever slow down in emacs. I also noticed the main
menu bar would disappear when I changed modes.

Now my .emacs file throws this error when emacs starts:
Debugger entered--Lisp error: (void-function x-selection-exists-p)
   (x-selection-exists-p)
   (and (x-selection-exists-p) (not buffer-read-only))
   sit-for(120)
   command-line-1(nil)
   command-line()

Any idea what is wrong?

Are you running version 21.3.50 from the CVS? Perhaps you are running
one compiled by Fink or one from a binary version obtained somewhere
from the Web.  Neither is recommend because these version are very
out-of-date (at least half a year old).  I have no control over people
who provide such versions and don't update them, although I have
invited them to do so openly many times.  I end up getting questions
on bugs that are fixed already.

Many problems have been fixed in the current version, including the
definition of x-selection-exists-p and keyboard response problems.
Would you please take a look at the following web page

for information on how to obtain and build it.

You can also write the maintainers of these "distributions" for help.

Also these discussion forums will soon not be used.  Please see the
above web page for where to obtain help on Emacs for Mac OS X.
