No, it's not -- good point.  As I mentioned in another message, we blow
away our development databases fairly regularly by replacing them with a
copy of our live database.

If you're thinking there must have been something wrong with the index
file in my "open w/ index file" case last week, I doubt it -- the index
file was regenerated from scratch every time I ran the "open w/o index
file" case (well, strictly speaking, the close regenerated the index
file).

However, the .fs file I was using last week was freshly packed; the one
I was playing with earlier today was not.  Apart from that the only
difference was a few days' worth of traffic on our web site and a few
days' worth of changes to our database update script.
