Blobs with CachedUpdates

Attempting to use any kind of Blob with cached updates turned on
yields an "invalid blob handle in record buffer" error during the
post.  Turn off cached updates and use a live result set instead,
and problem goes away.

We've reported it to Borland via their web site, but for some reason
I'm dubious about that actually doing anybody any good.  Anybody
here dealt with this before?
