Thanks for that heads-up, dlhotka, not seen before. I guess it stands to reason, with WinXP having a low processing overhead and happy in one core, where Mac has always been higher. I wonder if Win8 is asking for more, as it is reported to be so much more responsive?
Two core for 10.6 when running under 10.8 in two core is going to be pretty squeezie on my four cores, when I also need WinXP. Sounds like a good excuse for a Mac Pro with four, four core, processors. 
I'm mulling staying in 10.6 instead of 'up'grading, as much as I like MoLi superficially, and just use it virtually when needed. It's just the hassle of swapping the SSD back to SnoLep ~~ that's what you get for rocking the (setup) boat, I guess.
