problem with banner resizing.
 

My site is www.batterypoweredmotorsports.com. I have an issue with the top portion or banner portion of my site. When you view it in a maximized window its fine* but when you minimize it* it breaks as it trying to compensate the change. How do I fix this?

Also* I would like to change the description in the IE tab. Right now it says " Electric Motorcycle Forum - Discussion Forum" I would like to delete the Discussion forum part.

Thanks!
