ESC is already running, but is not responding.

新安装了redhat企业版5， 每次重启**Xwindow时，出现如下**框： “ESC is already running, but is not responding. To open a new window, you must first close the existing ESC process, or restart your system.” 根本解决方法是：yum remove esc

引用国外文章：
Disabling "Smart Card Manager" n CentOS 5.3 there is a new "Smart Card Manager" window that pops up when I log in to KDE. Is there any way to disable it? As root, run "chkconfig pcscd off" then "/etc/init.d/pcscd stop" or "service pcscd stop" Disabling pcscd didn't get rid of the pop-up and system tray icon. However, I did "yum remove esc" and that did the trick.
有人说：这个是你的系统里有一个程序一直在重启动开启一个新窗口，而这个程序本身很可能有问题，一启动就会被关闭，所以报这个错误，一般都是火狐，实在不行你整个把火狐卸载了试试，或者你进入Xwindows后在命令行下查一下你的所有启动进程，看看有没有有错误的
