Textarea problem in Internet Explorer

IE adds <hasbox> to html tags in WYSIWYG editor

[gcan]

I have installed NicEdit WYSIWYG editor.
For some reason Internet Explorer adds <hasbox> to all tags.

For example, if I change font size, the html code in Internet Explorer looks like this:

<FONT size=1 hasbox="2">Test</FONT>

In all other browsers it's just:

<FONT size=1>Test</FONT>

What is "hasbox" and why Internet Explorer adds it to the html tags?

Thanks.

It's only a WYSIWYG text editor to the extent that it allows formatting user editable content.

"NicEdit is a Javacript/AJAX inline editor to allow easy editing of web site content....."

I would assume that if you crack open the .js you will see that the instruction for this insertion into IE is in the .js
