KDE system update notification disappears shortly after login

Hi, I'm using opensuse 12.3, not sure what version of KDE it is but it's whatever comes with 12.3

A minor annoyance, but I've found that after login when I get software update notifications on the taskbar,
if I don't click on it within say a minute the notification disappears until I next login.

I find this annoying if I don't want to install the updates immediately, e.g. I want to get on and actually
use my computer rather than sit around for them to install.

Is there some setting where you can get the notification to persist?

I've had a look in the KDE system settings panel and can't see anything there,
apart from getting the taskbar to flash which I don't really want.

Thanks
