Me again. Still have an issue with pasting text into GroupBox. Also, I found the same error with the Layer element created by the 'Insert Layer' button. Again, pasting text with the keyboard shortcut (control + v) clears the editor and displays a javascript error. The page needs to be refreshed for the editor to function.
This is important because we are enabling most, if not all, of Cute Editor's functionality to our clients and a lot of them don't know about context menus so they can't be bothered to be told to right click and select paste or to use the paste button instead of using a keyboard shortcut.
Thanks again!
