>I noticed that when I issued REINDEX on a few tables (which had not been REINDEXed for quite some time) the SIZE of the CDX file became considerably smaller. Does REINDEX do some kind of optimization that would result in this as a matter of course or might the change indicate a problem of some kind? I can't seem to find any technical reference in MSDN that explains this.

Indexes can become corrupt.

Who knows how that would impact the size.

To be safe you should drop and re-create your indexes from scratch.
