Hello Joe,

on my 2010 Win 7 Laptop an idle Squeak 5.0 with several windows uses no 
cpu and a Squeak 3.8 with a MagnifierMorph (screen magnifier) uses 
between 2 and 3 percent.

In 5.0, Tools, ProcessBrowser, right click in the pane with the 
processes, auto update, right click again, start cpu watcher and see who 
uses CPU in Squeak. I have 14% UI process and 86% idle.

OTOH at 6% CPU no laptop should get hot and turn on the fan. Maybe you 
only see your processes and some system process got busy. No Mac so no 
idea if this applies.


Cheers,


Herbert
