Answer 1

SharePoint rich text fields start out as text areas, and some javascript in the page load event replaces them with a different control if you are using a supported browser.
With an update panel, the page isn't being loaded, so that script never gets called.
Try hiding the section using css/javascript rather than the server side visible property. That generally lets you make whatever changes you need to the form without sharepoint seeing any changes.

Answer 2

<SharePoint:InputFormTextBox ID="tbComment" CssClass="sp-comment-textarea" runat="server" TextMode="MultiLine" RichText="True"></SharePoint:InputFormTextBox>
<%--textbox for temporay focus - trick the IE behavior on partial submit--%>
<input type="text" id="<%= tbComment.ClientID %>_hiddenFocusInput_" style="width: 0px; height: 0px; position: absolute; top: -3000px;" />
<%--tricking code that makes the 'SharePoint:InputFormTextBox' to work correctly in udate panel on partial podtback--%>
<script id="<%= tbComment.ClientID %>_InputFormTextBoxAfterScript" type="text/javascript">
(function () {
// where possible rich textbox only
if (browseris.ie5up && (browseris.win32 || browseris.win64bit) && !IsAccessibilityFeatureEnabled()) {
// find this script element
var me = document.getElementById("<%= tbComment.ClientID %>_InputFormTextBoxAfterScript");
if (me) {
// search for script block of the rich textbox initialization
var scriptElement = me.previousSibling;
while (scriptElement && (scriptElement.nodeType != 1 || scriptElement.tagName.toLowerCase() != "script")) {
scriptElement = scriptElement.previousSibling;
}
// get the content of the found script block
var innerContent = scriptElement.text;
