As an administrator for forums elsewhere, just wanted to let you know your efforts are appreciated!!!
A few minutes ago I generated another error banner using IE9. This one said: The following error occurred: Security error (press the back button and refresh the page) Sorry, I forgot to take a screen shot this time but you'd see it in the log anyway. EDIT: Nope, I still can't edit using IE. Error on create cache, security error, just great.... This is as frustrating as using Windows Vista OS *shudder*
Im away to monday night. Will take a look into it. Your only one showing up in error logs, wonder if its a setting or addon you have for ie9 if thats the only one you have an error with?
