Someone asked me the same thing yesterday. You really can't treat the layout maker the same way you treated the old one. You have to mess around with it to make sure everything comes out okay.
Yeah, it isn't working well for me, either. It will look fine in the preview, and I save it and it goes back to how it originally was, or it will set to something totally different. :/
v that's another thing- the text isn't white for me. It is black. Someone told me that my text was white, and it's black. I don't know what is wrong but it is the layouts and the way they work with the different browsers or something.
