[opensuse] A GNOME update applet question

How can I set up SUSE updater to check for updates for some period? Default settings is set to check for update every day, but the problem is that it checks for update after every reboot, which is very annoying. I tried both options, "every day" and "every other day", but the result is the same for both options. Is that a bug, or it's a feature? :) Cheers! -- Igor Jagec
