Appears that the grid lines are being treated errorneously as bezier curves.

When I load this file into IFFMaster I can see the gridlines OPLY chunk (screenshot attached). It is a sequence of INDICATOR/0x00000002 (IND_MOVETO) followed by the co-ordinates, eg. 0.0,500.0,500.0,500.0.
There's not anything obviously wrong with the contents of that chunk, and neither can I see any bezier curves at all in the entire file (the graph is made up of very short straight lines).
The file is however failing to open in anything other than MetaView due to IFF parsing errors.

After a bugfix in my datatype, this file displays ok in Multiview (except the gridlines don't display at all). In MetaView I see weird bezier curves that shouldn't be there (and an error), and in ProVector the grid displays but the lines do not (however I'm not confident the display is working correctly here, it's an old program).
