    Hello Kennet,

    Is it possible to open a support ticket and to send us a sample project where this is reproducible. We are not aware of such problem and is most probably related to a specific scenario.

    All the best,

    I got a similar issue and found the solution here

    http://www.telerik.com/community/forums/wpf/draganddrop/setallowdrag-crash.aspx

    I suggest that Telerik improve a error message
