Posts are redirecting to ads in Opera

When my site is viewed in Opera browser with In Post Ads activated, the post loads and then quickly redirects to one of the ads (i.e. one of the in post ad post that I have set up).

As far as I know, this problem is only apparent in Opera Browser. I have also tested IE, FF, & Chrome.

Is anyone else having this problem? I have had to turn ads off on the sites as it is putting my adsense account in jeopardy. The plugin is displaying ads on pages that do not have any content but the ad, (when the visitor is using Opera browser.

Please help.
