Is it COMSOL or MS W7 that saturates the context switching ?

Hi

A few months ago, just afer receiving 4.0a I could launch a serious structural analysis and see all my CPU's turn green 99% occupied by one task: Comsol MP on my multicore WS.
Observed with Sysinternals ProcessExplorer. Only CPU0 had some red flashing, and the task run smoothly.

But today, a few OS upgrades (MS usual, nothing fancy) and COMSOL upgrades to latest, I see som grass type 10-30% CPU occupations with a "context Switch" counter flashing between 1 to 4 millions / sec !? for my "heavy" tasks. Even the ventilator does not turn on, and today it's cold, would mind the extra heat ;)

Is this only a present for me, or have you others noticed some changes too ? and could it be the OS or COMSOL ?
