I agree with you on this. the only way I can think of to do this would be to actually have multiple VFP executables running independent of each other (if synchronization was needed, some sort of semaphoring could be used to signal the completion of a spawned task; you could use API_APPRUN to launch another VFP session using the LaunchApp method, and then poll for its termination using the CheckProcessExitCode method. This has the advantage of letting two things go on independently, but obviously, there'd be multiple copies of the VFP environbment up and running, and competing for CPU cycles and memory.
