Thanks Chris,
I was just looking for that confimation.
There are more bugs in the spirit.ocx, ever tried to read the sensor mode ? Well you'll probably get the sensor mode multiplied with 32.
I've just reported these bugs to Lego.
I've also asked them for a bug list and if they've any plans to fix them.
I'm curious if I get any valuable answers.
I'll keep you informed.
