I have a new Dell XPS workstation running Windows 7 Ultimate x64 SP1. It is important to note that this issue only occurs with Internet Explorer 9 (x86), the tabs work correctly with Internet Explorer 9 (x64).
When clicking a link a new tab opens up, but nothing is displayed. This occurs with any/all links that open a new tab.
Troubleshooting thus far;
Uninstalled & reinstalled Internet Explorer 9 - no change
Removed all add-ons (Google toolbar, etc) - no change
Reregistered IE9 DLLs - no change
I have checked many websites and tried several of the suggested solutions (see above) but nothing has resolved the issue.
