Buffers Window Frame problem

Hi, I'm getting a strange and rather hard to describe problem with emacs-version "21.5 (beta14) \"cassava\" (+CVS-20030610) XEmacs Lucid" on a RH9 system. I can't reproduce it with "vanilla" so it could be some subtle interference with elisp problem as well. (Works OK in 21.4 though!) The problem is that when I have multiple windows in a frame the buffers can get switched with out me doing anything. My guess is that is has to do with the update of the modeline where I have the time displayed. (display-time-echo-area = t) When the time is updated in the modeline I can get a buffer switch in one of the windows. Like when I use Gnus the *article* and *subject* buffers might be replaced with the *Group* buffer. Yours -- %% Mats
