Hi Frank,

Valentina 1.x do not use double CPU in true way.
This will present in 2.0 and macho only version.

You see, I think that MacOS X itself try balance loading of CPUs.
I see this the same almost amount of usage very often, for many apps.

In the same time note, that REALbasic run plugins it seems in separate
thread. If this is true then threads can use own CPU.
