Mouse scrollwheel changes RadDropdownList even when you click away

Hi,

If you have a RadDropdownList on a form at run-time and the user clicks on it, and then decides to click on the form itself (not another control) the mousewheel can still be used to change the RadDropdownList contents.

This seems like it could lead to accidental changes to the RadDropdownList's contents. 

Is this by design? Is there a simple way to prevent this behavior?

Thanks,

-Lou
