I've had this issue in the past, and I suspect has something to do with the buffer
scrolling. I have not yet been able to pinpoint the exact error, however.

The procedure you want is in dataset.inc, line 1634

Procedure TDataset.ShiftBuffers (Offset, Distance : longint);

Subprocedure 'shiftbuffersdown'.

I currently do not have enough time to look at it, but if someone else
has, the above info may help to pinpoint the exact problem.
