Hi.
I created this interface:

I am using a few UserControls to make this.
And and you can see, it has a propertyGrid panel. My problem is that I can access every property of it, but I can not write anything inside any of my controls. I also have a richtextbox and I can not type on it. Mouse input is working fine and I can click inside the richtextbox and the focus go to it, but when I try to type, nothing happens.
This problem is also happening with simple textBoxes, richtextboxes and any controls that accept text.
Here is a simple project showing this. It has a button and a RichTextBox. Just click inside of it and then try to type any text. Nothing will happen.

Does anyone know a way to fix this problem?
Thanks
