Code View on Dreamweaver and Safari

Does anyone know something about Dreamweaver and why the code appears completely illegibly all over the screen?Same when I view>source in safari. Am currently learning XHTML and PHP and need to accurately view the code in dreamweaver, instead I have to use text edit and paste into Dreamweaver as the code is illegible. It worked before so there must be something simple to change it so I can see it clearly!

Any help be great. Is there a site like Flashkit but for Dreamweaver?

Thanks

have you tried to go to the Commands menu and Apply Source Formatting it can help clean things up a bit. although dreamweaver is notorious for creating messy code.
