You must have asyncwb running in your startup. Can't recall if it was 3.5BB2 or 3.9BB1 that introduced it, but - in any case - you should have 3.9BB2 installed for optimum experience so asyncwb would definitely be in there. I'm also not quite sure it is copied during installation, so you should check your installation disks/BB archives and find it and copy it yourself.
