Thanks for the reply Chris. Are you suggesting running the task in a *separate* process instead of a separate *thread*? Because if that's the case, I will have to share data (and possible memory) between that new process and my "master" process since they depend on one other.
Yeah I will sure post it if I can find an elegant solution.
