Help Social Hub not opening default apps?

[DemonTraitor]

When using Social Hub, if I click on a feed it asks what I want to use to open the feed - Exampl: If I touch a Twitter feed it asks if I want to use "Dolphon", "Internet", "Twitter". If I touch Twitter, it just opens the stock browser and shows the feed in there. I have looked at the Default Settings in Application Manager, and these are greyed out.

Anyone else getting this problem?

Thanks
