I have the English version of this on my computer...is it convertible to Thai and back? Or does a Thai version need to be installed as well? Our other back up laptop is off to CMU this semester and that version has the Thai headings, which I can not use at all. I don't know if there is one-key fix for this or not. By the way, this keyboard has both types of characters on it. It would be very nice if both versions could be available for use. Do any of you tech savy types know? Thanks for any advice. pe
