Hi 

I have a simple WPF application which is having combobox on xaml. Following is the XAML code.

           
           
       

The problem is Combo does not respond to keyboard  inputs quickly e.g. if you press any two keys immediately (Y & N ) one after the other instead of second only the first combo value get selected. So the problem is only when the multiple combo values are selected within a fraction of seconds.
Any help will be appreciated.

Thanks
