I'm doing ok with my buildings, but I have some small black specks. It's as though the transparency isn't correct in places. I've checked them over with readbif 23c once the bif is made but the transparancy seems to be correct in those areas where the black specks appear. I've resolved it on one icon by colouring the specks with a foreground colour. I'm using PSP v5.0 to edit the files and saving them as .png then saving them as bmps using irfanview. If I save as .bmp in PSP the pallettes get mucked up. This seems a bit long winded. I don't have any other paint program so i'm not sure what else to do.
