I have a form that contains a UltraDropDownButton that displays a user control that also has a UltraDropDownButton.  The sporatic behavior that I've been noticing is when you click on the nested UltraDropDownButton,  the parent dropdown will close exposing the nested dropdown as if was a detached window in the upper left area of the form.  The controls on the detached  dropdown function properly but the data is not persisted.  When I click on the parent UltraDropDownButton, the problem is corrected. 

To date, I haven't noticed a pattern causing this behavior.  What do you suggest I do to correct this problem?  The app is using the controls from NetAdvantage Winform v10.2.

Thank you
