Hi, i am happy user of Centos 5.1 . i have installed Zimbra , Zenoss and webmin for testing purposes. Everything was going fine until yesterday when ever i want to go to yumex Gui it does not open, same with add and remove software when i click it , it does not open. also when i go to "services" gui same is happening. Yesterday i updated the system and rebooted still the problem remains. everything is fine if i do it through the terminal. but when i want to access services , network , yumex , add & remove software they dont start. other programs like Ooffice work. if i check in the terminal they are working. So what is happening ? please help in this matter. i am using centos 5.1 on vmware server 1.0.3. will install on a production server soon. Thanks
