Clicking on links problem

I have probably asked before a while ago. But can't find a solution so far.
When in Skype, Tweetdeck etc etc I click on a link. But nothing will happen.
Same for emails etc.

Did some internet settings resetting etc. So far, no changes.

Tips or hints?

Open the Default Programs settings in the control panel and check that you have a browser associated with the HTTP protocol.

Wow, worked like a charm, thanks!!
Except, it doesn't see my Chromium browser. I selected Firefox instead and that did work.
Any thoughts on how to make it see the Chromium browser?

It was before. It changed to Firefox. Changed it back to Chromium and didn't work anymore.
So back to FF as default, works again.
Seems Chromium is not playing nice here.

Will make FF my default and leave it at that.
Thanks again Nossid
