up2date shows packages in the "available package updates" to update when those are older the the currently installed packages. eg: #rpm -q gnomeicu gnomeicu-0.94.1-0_helix_1 and up2dayte shows: gnomeicu 0.93-5 and many similar packages which are installed form helixcode. this is a _new_ error, original (7.0) up2date do NOT shows these packages. ps. there is not any help information anywhere and why up2date retriving the up2date database rhn's UI is frozen which means it's not even refresh it's display (and I assume this database getting bigger in the future so even on a fast connection it can be slow).
