When working with the latest version of redhat 6.1, the system locks up if you move the mouse pointer over the "gnome" submenu on the KDE desktop, you don't even have to click a mouse button..
Remote logging is possible through Telnet and killing the following process (kdm, kpanel) allows me to login into KDE or Gnome desktop again with no problems. This is on a DS10 Alphaserver system with the Elsa Gloria (3dlabs) card. Norberto
Fixed in 1.1.2-16 - the problem was a bug in TryExec handling
