The most common cause of this issue is not restarting the computer following the installation of Internet Explorer 7. It seems that if you do not restart Windows immediately after the installation has completed, it causes some side-effects, particularly the error you describe. This may not have been your fault, as the Internet Explorer 7 update may have been automatically downloaded and installed from the Windows Update website. After the update was installed, and you were prompted to restart, you might have elected not to restart (as you did not realise the implications of such) and thus now the program does not work correctly. In this case, the workaround for the issue is to uninstall Internet Explorer 7, through the “Add/Remove Programs” control panel, and then reinstall Internet Explorer 7. Make sure you restart the computer once the installation has completed!
Apart from reinstalling Internet Explorer 7 I was unable to find any other workarounds for the problem. Some users have reported having to reinstall Windows, but this is only in extreme cases. In the worst case, you may have to just uninstall Internet Explorer 7 and go back to using Internet Explorer 6. However, I imagine you might like the new Internet Explorer 7 features such as tabbed browsing. Should this be the case, and you are unable to resolve the problem with Internet Explorer 7, perhaps another alternative is to try Mozilla Firefox (http://www.mozilla.com/firefox
). This is a very popular free open-source web browser, with many of the same features (tabbed browsing, RSS integration, etc.). This could be a useful compromise if you are still unable to get Internet Explorer 7 to work correctly.
