I am finding serious problems with your controls. I have found two already (how many more are there?) that don't scroll inside a window. The Button control is one and the other is the ColorPicker.This is a serious issue. IN IE, and yes I'm using IE 11, your Button control is not scrolling and neither is your ColorPicker. I have tried setting the position to relative and it still doesn't work. I am using v.2013.3.1114.40 in VS 2013. I would appreciate any advice you can give to fix this issue.
