Thank you for your quick reply.
I have checked the url, the error is still coming for me.
I am using IE7 here.
First you have to uncheck the property "Disable script debugging (Internet Explorer)" in IE7-Tools Menu - Advanced Tab.
Then go to http://cutesoft.net/example/general.aspx, here the cute editor contains already a table there. select that object and right click on that and click the properties menu, then insert 1 row or column through that property window, then click cancel button, the error will come.
thanks
