Thanks Adam,
That fixed the file filter problem for me. However, now the client is running into errors trying to upload exe's. Ive tested and it gives a simple permissions errors when the upload is done. It seems to be isolated to CuteEditor since i can use our regular asp.net upload control and upload an exe with no problems. Im assuming this is a security feature of CE and makes perfect sense. Is there a way for me to disable this security feature? Im just using CE for input on the backend of the site, only site admins will have access to this control, so im not worried about people uploading malicious files. Thanks for your help.
