cannot ignore software updates

when using opensuse 11.2 i get a popbox saying there are security updates ready to install. if i right-click on each update, there is a "ignore this update" button but i cannot click on it because it is greyed out.

why can’t i click on ‘ignore this update’?

I don’t use the updater applet. But could you be a little more specific. What updates do you want to ignore.
