Of late, I keep getting a message "Internet Explorer has encountered an error and has to close. You will lose any work you were working on. We apologise for any inconvenience" or words to that effect. It's only on this site, and only on this computer (which I recently changed to). I've tried the usual empty cookies, delete temporary files, etc, but it keeps coming up. It happens about half the time I visit the site, and usually within a couple of minutes. Any ideas?
