It is odd, I think, that lowering the priority of the process is not enough.
In my experience using the code I posted above is sufficient. I use it when
I run run parallel programs on a network of non-dedicated machines and I
have not yet received a single complaint about my programs not yielding the
CPU to other programs. Windows appears very efficient at excutig higher
priority threads before lower prioriy ones. Does your application use
multiple threads so that some might remain at high priority or do you use
library routines that can sit on the CPU while waiting for a response from
the network, or similar?

Kind Regards,
