Hey, you are correct! The Windows version's message pane is returning the wrong
values; RTR *is* using both of my Win 7 machine's 2 threads. (I did a test to
confirm this, changing v3.8's Work_Threads from my default of 2 to 1, and a
complete loop of the first RTR animation proceeds twice as fast.)

The message pane reports only this info, regardless of the Work_Threads setting:
       Parse time... using 1 thread
       Bounding time...using 1 thread

Thanks for the tip. Now, I can do some RTR/radiosity light-patch 'quality' tests
comparing 1 vs 2 threads-- which is not exactly a *definitive* test set-up,
compared to a really *multi*-threaded computer like a Core i7,etc...
