>> As you can see a few lines above the value of mask depends on _cell.is_highlighted and _cell.state. You should output these two values as well. Next it could be either _highlightsByMask or _showAltStateMask. Sou you need to check these values as well. If they are zero you should go back to the decoding method and see wether these values get decoded correctly. The best way to check is to do the same on a 32 bit or 64 little endian system and compare the results. Form files should decode the same for both systems.

You should concentrate on the _highlightByMask which gets decoded in line 1905 (_showAltStateMask is handled just below).
