Hello, I'm running 9.1 Professional using KDE as my desktop. I rarely reboot my computer, and I do a YaST update every couple days (whenever the SuSE Watcher icon in the system tray changes colors). Normally, YaST launches fine. But every few weeks, YaST refuses to launch. When I click on the YaST icon (a link on my desktop), the little icon, that indicates an application is starting, bounces around for several seconds, but YaST never starts. I tried doing an Alt + F2 to launch YaST from the Run command, but the same thing happens. The only way to launch YaST is to log out of KDE and then log back in. As soon as I do this, YaST launches normally again, for another few weeks. And then the problem occurs again. It seems that whatever mechanism KDE uses to launch YaST gets confused after KDE has been running for a few weeks and YaST has been launched several times. (Other applications launch fine even when YaST won't.) The last time this problem occurred, I looked in /var/log/messages, /var/log/warn, and /var/log/YaST2/y2log (via tail command), but there were no error messages logged. I tried launching YaST from a CLI (using sux), thinking that I would see some error messages. YaST launched successfully from sux, but the text version, rather than the graphical version, launched. This problem isn't unique to 9.1. I've had this problem with older releases (9.0, 8.1), but have never spent too much time trying to resolve it until now. It is easy enough to just log out of KDE every few weeks when the problem occurs. But it is still very annoying. Has anyone had this problem or have any ideas what may prevent YaST from launching on occasion? Thanks very much. Dom
