I have not played with the 3-D stuff yet (sniff, sniff) but it may be to
because the A2320 does the scan-doubling in Amiga non-interlaced display
modes and the FlickerFixer (TM) only trys to de-interlace all the time.
This may effect the 3-D effect since the LCD glasses open and close
their shutters at the field rate and expect each field to be DIFFERENT
and not de-interlaced together.  That is only a guess though.....
