CuteEditor.dll version 6.0.0.0

If this is specified in the aspx page it throws the following compilation error:

BC30456: 'PasteBehavior' is not a member of 'CuteEditor.Editor'.

Here is the code snippet:

<CE:Editor id="CuteEditor" EditorOnPaste="PasteText" runat="server" width="550"
               AutoConfigure="Minimal"
               AutoParseClasses="false"
               XHTMLOutput="true"
               UseSimpleAmpersand="true"
               UseRelativeLinks="true"
               ShowPreviewMode="false"
               ShowHtmlMode="true"
               RenderRichDropDown="true"
               RemoveTBODYTag="true"
               EnableStripScriptTags="true"
               EnableBrowserContextMenu="false"
               BreakElement="P">
           </CE:Editor>

If I specify this setting in code behind it works in IE 7 but is completely ignored in Firefox 2.0.0.6:

Me.CuteEditor.EditorOnPaste = Global.CuteEditor.PasteBehavior.PasteText

Thank you for any help.
