software issues

Iam new to linux and i just installed opensuse 11.1. Everytime i click on install software there is a pop up that says system management is locked by the application with pid 4350 (/usr/lib/yast2/bin/y2base) close this application before trying again.
What is causing this issue and how can i fix it.Any help is greatly appreciated.

In the sys tray, see the updater applet
quit it

I never use it, so mine is disabled from even starting. I just use yast - software management to update.

see if that helps

when i go to yast and click sofware management i get this same thing. I ran a repair installed system but that found nothing wrong.

I also quit the updater applet and that didnt help either.
