buttons and icons in window bar forced to center

Hello,

I recently kicked Bill Gates to the curb and loaded Ubuntu 7.04. First, I have to say I love it! Now for the bug:
After restarting the my laptop (asus) the Grub said my /sda1 hadn't been checked in 34 times, then it started to "force check". It took about 7 minutes. Once I got to my GUI I discovered that several system setting (GUI looks) had changed. Ie: no icons in top panel, no files would show up in windows. It is as if the OS was still there but all the default setting were gone. I went into settings and resolved many of those problems. However, the Maximize, Minimize and Close buttons on the right of each window bar and the icon on the left and skewed to the center. Depending on the size of the window the buttons and icon will cover the text in the center. I'm now looking for a command line fix. Does anyone know what I can do from here?

Any assistance is much appreciated. Thank you.
