Default Selection

[VTEC4ME]

You know when you click on a link in your messages (handcent sms), a box prompts you what program you want to use to open it? At the bottom of the box it asks if you want to make it as a default selection for future selections. Is there a way to undo that?
I thought by going under Manage applications and selecting Clear defaults would do the trick, but it doesnt.

My issue is, that if someone sends me a website link, it will open it under the android market and not thru the internet browser anymore.
