By default, the navigation button (the joystick) found on almost all PDAs is bi-directional. You can only go up or down. There is a registry setting that can change that to a 4-way navigation which comes in handy when you access sites not optimized for mobile access. Here's the trick:

Change the value for this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Interne t Explorer\Navigation\"4-Way Nav"=1

To

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Interne t Explorer\Navigation\"4-Way Nav"=0

Soft reset your device.

Enjoy!
