Button will not launch website in html mode but works in .exe mode

Hi,

(Running Adobe Captivate 3)
I have e-learning content that I'm creating and I'd like to launch a website through a button on this presentation. I have inserted the button and have gone into the options to "open file or url" and I also set option to open in "new window."

1) When I export to .exe the button works just fine and the website will open as its suppose to.
2) When I export to .html, and open it on a web browser, the button does not open a new website. (Using IE7)


Does anyone happen to have a solution to this? This does seem like a simple problem and hopefully with a simple answer.

Thanks

Danny
