    I have implemented load on demand submenu items using webservice.  It is working great in FireFox.  The submenu returns and displays in less than 1sec.  In IE7 however, it averages 6-7secs to load the submenu.  This is not really acceptable for usability.  Is this common?

    I have found the cause of the issue but not the solution.  It seems like Telerik is not compatible with ExtJS framework.  When I include the ExtJS script, the webservice slows down by ALOT in IE7.  Without the ExtJS script, it's almost as fast as FireFox3.  I would send in a sample project but my support subscription just expired.  Is this something Telerik can fix?  I do not see the same issue between ExtJS and other 3rd party controls.
