This issue causes inconvenience among users. Block elements in the content cannot be edited properly when used in the RadEditor.

You can workaround this problem by overriding the setActive method of the RadEditor's object:

<telerik:RadEditor runat="server" ID="RadEditor1">
</telerik:RadEditor>

<script type="text/javascript">
	Telerik.Web.UI.RadEditor.prototype.setActive = function () {
		var $T = Telerik.Web.UI;

		if (this._emptyMessageContainer) this._hideEmptyMessage();

		if ($telerik.isIE && this.getSelection().isControl()) return;

		var curArea = this.get_mode() == $T.EditModes.Html ? this._getTextArea() : this.get_contentArea();

		if ($telerik.isIE) {
			var activeElement = this.get_document().activeElement;
			if ((activeElement && activeElement == curArea) ||
			$telerik.$.contains(curArea, activeElement)) {
				return;
			}
		}

		if (curArea && curArea.setActive) curArea.setActive();
	};
</script>

Problem:If I used master page and put there RadSkinManager how can I used designer in page inherit from the master ?
Solution:I can only use the designer in the page where the control is situated.
Suugestion:Make proxy for RadSkinManager like RadAjaxManagerProxy

When a user works with large content in the editor and pastes a word in the end of it, the page and content area are scrolled to the top. This causes an inconvenience for the editing behavior, the user should scroll down to continue typing or editing.
