 The problem with this is that the so-called ‘pause button’ does not do that. At least it would not for my case running Windows 7 Ultimate. The software continued using most of my computer’s resources even though I ALWAYS had it set to run ONLY when idle. Not really much of a pause button if the software keeps running at such a highly demanding level. I’d expect a true pause function to run only a trivial routine listening for activity, such as watching the CPU for periods of inactivity of longer than a minute.

I would try rebooting the computer to see if it changes that.  But use the Stop Button as well.
