Favorites open printer dialog

When I click a link in Favorites a print dialog box opens. It will do this for all favorites old and new. I uninstalled and reinstalled IE9 and IE8 but the problem still persists. I ran the MS Fix It app to reset IE settings but still no help. I wanted to do a complete reinstall of IE but unfortunately I can't find clean install version of 8 or 9. It seems the only way to install is through the online install app at the MS website.
Running Windows 7 64 bit

Any thoughts?

Thanks Shawn,

Sorry it took so long, I merged the .reg script for the .url associations. Unfortunately it didn't correct the issue.

The issue started when I tried to install a stand alone version of IE 7 on my wife's system. She does web development and had to do some testing in IE7 for a client. The stand alone software was from Tredosoft. I searched their support forums and saw that others have had the same issue but there hasn't been any resolution posted. I even sent an email to tredosoft but never got a reply.

Thanks for your help

Thanks for the suggestion. Actually that was one of the first things I tried. Unfortunately the idiots who administer the network systems at my wife's company have disabled System Restore with a global group policy. Even if they were to switch it on there are no restore points because the group policy didn't even allow them to be generated. I questioned why the system admin would disable such a valuable support tool and was told they didn't want users to be able to undo updates and changes they push out over the network. I think the real reason is because they're control freak morons.

Thanks again for your suggestions. We've been able to work around the problem by using the History folders as a pseudo Favorites folder. It's a pain but it works.
