I'm having issues with the rad editor buttons overlapping at smaller window sizes. In attached image, look at the buttons to the right of the "Aa" button. Code is below.
<telerik:RadEditor ID="rtbBannerHtml" runat="server"
Skin="Silk"
ToolbarMode="Default"
Height="300px"
Width="100%"
ToolsFile="/ets/radcontrols/Editor/config/AdvancedBaseTools.xml"
ShowSubmitCancelButtons="false">
</telerik:RadEditor>
