I have the problem, that in my Editor, I always have a space on the right side of the EditorBody.

 

I tried to change it by FrameStyle or BodyStyle. No Success. The Border of the Frame and the EditorBody are correct, but there is still this space of about 10 Pixel and i dont know how to get rid of it.

 

Can you give me a hint? (Problem is IE 7 / 8 only, Firefox works).

 

Here an explaining picture of my problem:
