I install it per the instructions but the keys don't seem to rotate and the mappings are only correct on some screens.  For example, on the planet screens the mapping is correct for landscape mode and I can navigate the menu and recall the scout ship using the cancel key (corresponds to ESC in the desktop version).  When I'm on any other screen, the keys are not rotated properly and the only keys that seem to work are the arrow keys (in portrait mode) and the enter key.

Here is the PDA that I have:
Dell Axim X51V
