If the process affinity is 0x05 and I try and set a thread affinity of 0x03 this should fail and this will not be the case with the above code.
Oh right, okay. Harder for me to test as I only have a 2-core system, but I'll think about it and have another go.
Try Process Affinity 0x01 and set Thread Affinity 0x03 if you only have 2 cores.
