It's the perfect storm of stupidity. First off, it serves me right for using an antique web browser. Secondly, who's doing this shitty HTML coding? Thirdly, why is there an option for turning on such horrible response behavior in IE and why must it be so mislabeled? I get this problem due to bad javascripting in the page, then the page blanks out and is replaced by this message. The workaround is to turn off the option for blanking the page off, by going to advanced options and unchecking "Show friendly HTTP error messages" box. The actual solution is to go and download the lastest overbloated copy of IE and reinstall it, introducing God knows what new problems.
