This bug seems to be specific to Chrome. I'm currently using Chrome version 21.0.1180.79 m. RadEditor seems to be hijacking event handling to cause an exception in RadSplitter. The error that I'm getting is "Uncaught TypeError: Cannot read property 'tagName' of null". It's taken me a bit to narrow it down, but the following code reproduces. I'm using Telerik.Web.UI version 2011.3.1115.35

Steps to reproduce this error:
1. Click on the RadEditor to give it focus.
2. Try to slide the RadSplitter

Results: The split bar moves faster than your cursor. See stack trace below.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<head runat="server">
    <form id="form1" runat="server">
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server" />
        <telerik:RadSplitter ID="pageSplitter" runat="server" LiveResize="True" Height="800px" Width="1200px">
            <telerik:RadPane ID="RadPane1" runat="server" Width="250px" MinWidth="250">
                <asp:Panel ID="pnlNavTree" runat="server">                     
            <telerik:RadSplitBar ID="RadSplitBar1" runat="server" />
            <telerik:RadPane ID="RadPane2" runat="server" Scrolling="None">
                <asp:Panel ID="pnlRightPane" runat="server">
                    <telerik:RadEditor runat="server" ID="Editor"></telerik:RadEditor>

Could you please upgrade to Q1 2012 SP1 (version 2012.2.724) where this problem should be fixed?

All the best,
