I came across this error today. I found a pretty good workaround for the fix, though you should upgrade to Internet Explorer 8 to fix the issue if possible.
Example: “I’m trying to go to a website but it says “operation aborted.””
Resolution: This occurs because Internet Explorer 7 cannot handle one of the scripts on the website. The quickest and easiest way around this is to add the website to the Restricted Sites zone. To do this, go to Tools > Internet Options > Security > Restricted Sites and click Add to add the current website to the zone. You can also copy and paste a URL into the form. This disabled the scripts on the page so the user will not encounter this error.
