Vista - email hyperlinks using Outlook 2003 does not open in Internet Expl

I have a Dell Inspiron 1501, AMD 3500, 1.8 GHz, 446MB memory laptop running
Windows Vista Home edition. Every time I get a hyperlinked email using
Outlook 2003, the browser (IE7) open to a hanging blank page, and nothing
happens. I have searched these Treads and the Internet for a solution to
this problem. I have use various suggestions posted without any luck.

I had tried:
Open Windows Explorer.
Go to Tools | Folder Options | File Types.
However, there is no “File Types� tab in Vista. I have also tried the
Control Panel, but after making the association using the default programs,
it did not worked.

I also tried running
regsvr32 urlmon.dll
which was successful, but did not solved the problem.

Along with other regsvr32’s that I found on the web suggested to run; but
did not solve the problem

Any other ideas, or suggestions?
