Actually I should make one clarification. FRowsPerStrip is defined as a LongInt not a LongWord (probably should be a LongWord if the spec mentions 2^32-1). In testing I assigned MaxInt not 2^32-1 but this still worked fine (any fairly large number should work). I have ammended my copy of EnTifGr.pas to contain the following line:

CDefaultRowsPerStrip = MaxInt;

and that works fine.
