New Post: IntegerUpDown Keyboard Input Ignored

I'm using the latest version of Xceed.Wpf.Toolkit.dll and I'm having an issue with the IntegerUpDown as well as the DoubleUpDown. I'm unable to enter values through the keyboard. Only the mouse is allowed to change values.

Here is the XAML

<xctk:IntegerUpDown x:Name="UpDownQuantity" Increment="1" Height="22" Width="85" ValueChanged="UpDownQuantityOnValueChanged"/>

Is there something specific I need to add to allow keyboard input either through number pad or number row on keyboard?
