There's a registry key for this, but it can vary from one device to another. On my Psion Netbook Pro
(CE 4.2 .net
), for example, it's HKEY_LOCAL_MACHINE/Software/Microsoft/Shell/Autohide. If you're familiar with registry editors, you can look through the registry for a key called "Autohide" and change the value from 1 to 0.
(Edit the registry at your own risk, however.
