Problem with A85 Mode Selector

[orioane]

Hello,

I have a Canon A85 digital Camera and I have the folowing problem with it. Te Mode Selector (Dialer) is not working properly. There are a few modes apearing more than once and others aren't in their position.

Has anybody any ideea of what can I do. I think it's a software problem. Can the software be reseted or something like that?
