Desktop forgets theme?

Hi,

I've just installed Ubuntu 10.10 64-bit.

It came up saying I could install 2 proprietary drivers, one for my WiFi adapter (which works perfectly) and one for my graphics card - a Sapphire AIT Radeon HD 5770 1024MB GDDR5 PCI-Express Graphics Card. The driver is called ATI/AMD proprietary FGLRX graphics driver.

Before installing this driver I was unable to have Extra Visual Effects in Appearances. However after installing (and restarting) the menu bars are now in a basic light gray mode, rather than the sleek Ubuntu black. - Although Extra Visual Effects does now work.

I've tried rebooting, and I've had a look around in ATI "Catalyst Control Center" but nothing has worked so far.

Does anybody know what this windows mode is, how to change it back to normal and why it's doing it in the first place?

Below is a screenshot of my computer:

(This is also the first time I've installed Ubuntu on my computer, and am keen for it to work.)
