i have a program to learn thai , also writing system, it was always working ( and still) on my old computer, but since i changed to a new one, i am unable to get the thai characters ,instead i am getting ,fe D, F,% etc instead , i think it must be a setting problem somewhere , or can it be that my former computer had XP , and now i am using vista, it's not working?
thanks for any advice as i am not really a computer expert......
