I would suggest the following
1. try to get more info on field sizes.
ShowMessage(format(
'%d+%d = %d',[SizeOf(Integer),SizeOf(TDateTime),SizeOf(ClientRec)]);
2. I wonder if Integers are being stored as 64 bits. that's your extra 4 bytes...
Does the 'real' ClientRec have 5 integers in it.
3. Is one implementation with WordAligned data and the other not... IE are there
padding bytes involved in the new record (shouldn't be for LongInt and TDateTime
though AFAIK).
