>3. An hour later I realized I hadn't checked the performance meter, and did so. There was no disk activity. So now I figure it is *not* really doing anything, and begin to contemplate cancelling it.
>4. Concluding it was not actually doing anything, I cleared the task manager and suddenly it went to the next step?

>What I can't figure is:
>1. Was it "stuck" when I was gone (hence the "not responding" by task manager), is such a thing possible, cuz it ain't as far as I know.
>2. Is there any way that killing the task manager would have "un-stuck" it, or was this a major coincidence?

>This is a newly installed NT 4, SP 4, VFP 6 (no SP 3 on this machine yet). The "engine" is on a top-level form called from another form, which will be converted to an out-of-process server once I've run it a few times and am comfortable with it.

I've seen VFP show Not Responding in the task manager when it was really busy with data processing. Can you move the data to the local drive and see if maybe network access is what is taking longer than you think? Have you looked at using the profiler to see where your slow down is? Not know where or how you are getting to your data, I'm just guessing.
