Thank you for writing.
The difference seen in the screen shots is probably because the other person is using an older version of our controls. A version prior to the introduction of the RadColorBox and the respective editor in RadPropertyGrid.
The second issue is a known issue which we are working on. It is related to the font of your operating system and more precisely to the size of the font. It seems that cultures using hieroglyphs have a bigger font size and this affects the layout of our controls.
I hope this will help. If you have further questions, feel free to write back.
All the best,
the Telerik team
