Apper not asking for password then not letting me install software....

http://forums.fedoraforum.org – Hi peeps... don't recall doing anything... no idea why its done this... When I try to install anything with apper it starts looking at dependencies then throws up an error message saying authentication failed even though it didn't ask for root... I have a feeling that it's a setting somewhere because I installed yumex and that was doing the same thing... using FC19 KDE desktop... any help would be appreciated.. though bear in mind i'm still rubbish at linux (getting better! slowly slowly moving away from windows!! so close too...) so please just don't say "just do this&quot (HowTos)
