Having Problems with my Screen Painter

Hi,

I'm new to SAP and I'm still learning. I'm on this part of tutorial wherein I am trying to create a Screen using the Screen Painter. But the problem is, the interface of SAP in the book looks something like this:

But my interface looks different. I'm sorry I can't post the picture here but It can be well described. It looks like a "notepad" with horizontal lines.

Has anyone encountered this kind of screen painter? Hope someone could help me.

Thanks.
