That sure sounds a LOT like preemptive multitasking to me.
The ISR should have preempted whatever else was happening, but it would
not.
I donno, the fact you wanted the ISR to be triggered right away and it
was not, does not sound like a valid argument that the OS is not doing
preemptive multitasking. In that it worked sometimes but not others sounds like
you just didnt get the priority you wanted. The fact M$ could not help you
fix it also does not sound like a valid arguement either. It sounds like an
argument for a zillion other things, including against the use of windows.
