all "start\system settings" wont launch anymore.
i have somehow made my redhat 9 app dont start anymore unless i am in root account
recently i have messup with /etc/sudoers file and now all the programs which needs root password to launch wont launch unless i su to root under console and then lauch the program by typing redhat-config-XXXX to launch it.
i cant launch user and groups, sound card detector, printing, and etc.
i have already erased the entry that i have added in /etc/sudoers file but i still cant launch those apps anymore.
it usually will popup a windows asking for passwords but now it dont.
