New Post: Problems with IntegerUpDown.

1. You got it. Using "ClipValueToMinMax" to true will "cap" to the Maximum and Minimum values. This is not the default behavior because this property has been introduced later and we didn't want to change the current behavior of the NumericUpDown.
   
2. If I create a new project, add an IntegerUpDown and right click on it, the contextMenu contains text correctly aligned.
