You are probably using a Pentium with hyper threading capability. This
enables the processor to become a virtual double core and is seen as such by
When you access the task manager, it probably shows the CPU in 2 windows.
One will be working at 100% and the other at next to 0. That's because
Mathematica is using up all it can but on only one
""; processor.

Hope this helps.
