  Could you try with packed 24 bits. We don't have such a graphics
adapter here, the best is 24 bit displays. Otherwise the handling
of 24 and 32 images should be similar, could you try to recompile
from sources, changing in Thot/thotlib/image/gifhandler.c in function
MakeImage around line 1019 :

               break;
            case 24:
               bit_data = (unsigned char *) TtaGetMemory (width * height * 4);

to

               break;
            case 24:
            case 32:
               bit_data = (unsigned char *) TtaGetMemory (width * height * 4);

and check wether this simple patch works.

   thanks for your help,

Daniel
