Hi again Ivan. I understand, i used to use TinyMC also, and i must say CuteEditor is much better product. What you can try to do is
make a custom button (doesn't need allot of codeing) you can try to use this:
<a href="java script : javas cript : history.go(-1)">Cancel</a> This will bring you back to what ever page you was before using the Editor.
