Hello.

I am on Windows XP Sp3 32bit.
I use a Spacepilot Pro.
Driver is 3DxWare Release 3.16.2 (Driver version 6.16.1)
The Driver is active (shown in System Tray) and is set to
"any application".
Works perfectly here ...
[ I remembered that I said "custom Install" and ticked some
System Drivers, maybe that's the point ...]

Roland

Just for the records
a quick and dirty patch
