Thanks for the feedback, however the issue is not in creating custom dialogs from the editor but in running the Cute Editor within a Web Dialog or modal browser popup window.

 

If you create a new page called editor.asp that has the Cute Editor embedded in it and then open editor.asp from a parent.asp page with a BLOCKED SCRIPTwindow.showModalDialog("editor.asp"); command, you will see that the Cute Editor appears in the new popup window fine but when you click on one of the standard toolbar buttons that displays a further dialog such as Insert Image, it fails with a script error.

 

Thanks,
