I have a netbook PC and I can not see the whole header

I suspect that your screen resolution is currently too low to use XHeader.
XHeader needs a minimum screen size of 1024x768
If you are using a netbook PC, please plug in a full sized monitor to use XHeader.

If you are using a full sized screen, you can try increasing the screen resolution.

To do this in Vista:
Right click the desktop
Select Personalization
Select Display Settings


To do this in XP:
Right click the desktop
Select Properties
Click the Settings tab
