I have populated a drop down list of links.

However, if I try to put in one of the links on the LAST line on anything in the editor I get the following error.

It works fine if you are not putting the link on the last line of editor

htmlfile: Unknown runtime error

In Editor.htc.aspx

VS Debugger highlights this - element[_0xeacd[0x1e]]=Ox99 on line 144
