After some digging I see that my 'Error' message is generated by ASP.NET to protect against HTML that may have malicious code imbedded in it. You can prevent the error by setting the page directive 'validateRequest to false. However, then the HTML is not checked. Is this an issue using the Cute Editor? They advise setting up filters - regular expressions - that only allow specified HTML, if you set the directive to false. That would be a lot of code, I would think. Does Cutesoft have a take on this?
