This is happening at least once a day. It seems to happen when I close a web page (close a tab or click the close box for the entire app). I myself use konqueror, but it seems to happen to my gf also when she uses firefox and google scholar. This happens on two separate FC3 system (home machine and work laptop). The freeze up is pretty harse. Everything stops responding (no mouse or keyboard). No key combos do anything. Here is some system info, please let me know if I need to supply anymore. kernel-2.6.11-1.14_FC3 kdelibs-3.4.0-1.4.3.kde firefox-1.0.3-1.3.1 Does anyone else have problems like this? Any hints or suggestions? Thanks for the help.
