<p><dt><b>Undo/Redo doesn't work</b></dt>
<dd>We update a hidden field every time you make a change in the editor so the hidden field will be 
submitted when you submit the form.  The way undo/redo works in Internet Explorer it seems to reset
the undo buffer every time you use JavaScript to set the value of a form element or otherwise make
changes to the page.  Because of this the built in undo/redo functionality of the browser doesn't
work.  We hope to implement our own undo/redo functionality at a future point.</dd></p>

<p><dt><b>Relative paths are converted to absolute paths</b></dt>
<dd>Internet Explorer has a tendency to convert relative paths into absolute paths.  We've seen some
implementations of WYSIWYG editors that maintain relative paths "better" than others but certain operations
(such as dragging and dropping, etc) still convert relative paths to absolute paths.  We hope to find a
workaround for this in a future version.

<p><dt><b>HTML header info (eg: &lt;head&gt;, &lt;body&gt;, etc) doesn't get preserved</b></dt>
<dd>This is due to Internet Explorer and the way the editor works.  The editor already has a
HTML header of its own so inserting another one confuses the browser and the content gets thrown
away.  The best solution is to have another plain text textarea field for HTML header information.</dd></p>

<a name="bugs4"></a>
<p><dt><b>Some tags (eg: noframes, noscript, etc) doesn't get preserved</b></dt>
<dd>This is a result of how Internet Explorer works.  It seems to discard certain tags that it
doesn't need to display.  Because htmlArea reads the content back from the browser it cannot
preserve content the browser has "thrown away".</dd></p>

<a name="bugs5"></a>
<p><dt><b>htmlArea doesn't work with multiple textareas that have the same name</b></dt>
<dd>If you have two or more textareas with the same name on the same page and you try
to convert one or more of them into a WYSIWYG editor htmlArea won't work.  This is because htmlArea
looks up the textareas by name in the entire page, not just inside a specific form.  There's currently
no workaround for this.  We hope to resolve it in a future release.</dd></p>

<a name="bugs_ssl"></a>
<p><dt><b>Why do I get "non secure items" warnings when using htmlarea on a secure (SSL) https:// page?</b></dt>
<dd>This is a bug/feature of Internet Explorer.  Even if you get unsecure warnings your form contents should
still be submitted securely.  

<p>htmlArea uses an &lt;iframe&gt; to contain the editor and because the contents of the iframe isn't being
loaded off a secure site, Internet Explorer thinks the iframe is unsecure.  The problem is, the iframe doesn't
load anything off any site, it's blank, it doesn't even have a src attribute.  We just create an empty iframe
and then use javascript to update it.  We hope to have this fixed in a future release.

<p>Note: There's a clever workaround for this problem posted in the forum <a href="http://www.interactivetools.com/iforum/P3686/">here</a>.
The only issue with it is that can cause the back button to not work as intended (it goes back in the iframe first).
