I tried to reproduce the problem but to no avail. Could you please provide more detailed information on the subject?
Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
Under which browser and its version the problem occurs?
Are you able to reproduce the problem on the live demos? If so, could you please provide the exact steps the need to be executed in order to reproduce the issue?
Is it possible that you have disabled the context menus?
Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?
For your convenience I have attached my sample test page, could you please modify it to a point where the problem occurs and send it back? Also, the following video demonstrates my test, could you please see if I am missing something? http://screencast.com/t/a8kSKYWot
