Subject Re: [IBO] TIBOTable Access Violations when Using set ranges

If you are in a hurry for a fix then you need to send me a sample app that
will reproduce this problem.
The sample needs to work with minimal fuss on my part. If I hit any
significant hang-ups it will go into the queue with all the rest of the
items I have to look into.

In short, if anyone wants special attention in an expedited manner, they
need to minimize what I have to do in order to isolate and resolve the
problem. I've got lots of stuff piled up to do...
