This PROBABLY isn't it, but just out of curiosity, is your parent library "self" or "self_thr"?
"self" puts all your tasks in one thread, while "self_thr" puts each task in its own thread. If
you try to perform thread operations (like WaitForSingleObject) using "self", your whole program
will freeze, not just the calling task. For some (stupid) reason, "self" is the default.

I had to find this out the hard way.
