Wouldn't a better fix, over the long run, be to have POV ask how many cores
there are, then determine how to set both how many it uses, and what to tell the
OS, based on that? Or, just have an option to have it tell you how many are
available, and adjust how many you let it use, in the application? Having to
mess with the number of cores (especially if you have no clue), or monkey with
what the OS is looking at, after its starts a render, seems.. unnecessarily
fiddly.

BTW... Anyone know what Mozilla screwed up in the latest Thunderbird? This is
the first post I made in a while and had to make it on the website, because
Thunderbird kept filling in the fields for "reply to" and "newgroup" as "Scott
<spam&spam>" and "-blank-"... Frustrating...
