Problems with Irish Grid Ozi .map file

Hi, I'm trying to import a raster map that's been successfully calibrated and used in OziExplorer in Irish Grid / Ireland 1965. When opening the file, GlobalMapper (v11) complains that "The projection of the points in this OziExplorer format file could not be determined ...", and then asks me to select the correct one in the next dialogue, which I then do. The resultant map displays both upside down, and severely compressed in the horizontal plane. If I convert the .map file using another program (Ozi MapMerge) to WGS84, and then import, everything is fine.

Any ideas? I can send the OziExplorer .map file for investigation if required.
