For those of you who have reported here about problems with your browser windows suddenly going away in Firefox and/or SeaMonkey: Please send me all relevant hardware and software configuration details about your Mozilla installation as well as your version of CentOS. I am looking into a theory about why this might be happening and need more input. You can send these privately directly to me rather than the whole list if you prefer. I only need your h/w and s/w configuration information (what versions you are running on what kind of hardware). Thanks. mhr
