NullPointerException when dragging thumb outside window

[Ola]

Hi,

When I am dragging the SelectionEnd thumb on my RadTimeBar outside my dialog window I get a NullPointerException.

Maybe I get the exception because I move the mouse outside the window as I move outside the TimeBar.

Do you know of a workaround?

Hi Ola,

We have not had any reports about such a behavior so far. I created a small project and I was unable to get an exception. I am attaching it for your reference, I will ask that you update the project so that the exception occurs. Please explain what are the steps we need to make in order to get this faulty behavior. Can you also share with us which version you are using? Thank you.

Sorry to bother you. I had made some local modifications to the windows8 datavisualization resources that caused a crash after updating Telerik UI. It was nobodys fault but mine. Thank you for excellent support.
