[Chimera-users] Can't input anything under KDE

I am using Chimera build 2199 under KDE 3.5.2, and I can't input anything into the command line (and other input dialogs) of chimera. The linux distribution is Kubuntu Dapper Drake. If I get into the KDE environment with failsafe mode, everything is fine. And I remember chimera works fine under KDE 3.5.2 under gentoo. I guess some service(s) of KDE must have confliction with chimera, but I couldn't figure out which one. :( Best, Mingfeng
