emacs unstable

[Johann Spies <jspies@maties.sun.ac.za>]

I am running emacs (version 20.7 as far as I can dermine) on a
woody/unstable system and it happened twice that after cutting
a large block of text emacs just hang with the following error
appearing every few seconds (accomanied by a beep sound):

Timed out waiting for property-notify event.

Does anybody know what is going on here?
