Setting analogWrite on B0 sets any analogWrite value of B4 to 0

Hi Gordon,

We've been playing around with the PWM's and after resoldering our docking station because B4 and A6 don't like eachother, we encountered a new problem.

We reduced it to this:

firmware v1.73:

reset();
analogWrite(B4,0.5);  // works!
analogWrite(B0,0.5);  // The LED on B4 is dark now??
analogWrite(B4,0.5);  // works, both are on
analogWrite(B0,0.5);  // The LED on B4 is dark now??

Is this a hardware thing or is it in the firmware?

Cheers!
