I am using an Intel core 2 duo processor.

When I use the task manager to view the affinity of the number
processes it appears that all have only CPU 0 Checked. Further, when
I have two CPU intensive processes executing simultaneously there
seems to be very little activity on CPU 1 and CPU 0 is fully
saturated.

I fear that there is some setting that enables the task scheduler use
both CPUs that is not set correctly. What, if anything, can I do to
get some sort load-balancing between the two processors?
