Those are also issues, in addition to the encoding issue. A related problem, though, is OS support. If the standard specifies one thing and the OS implemented behavior is different, you've got a problem. This gets even worse if the devices hooked up to the OS behave differently from each other. If that happens, at some point you just "live with the problem" (which mostly, but not entirely, means not using that stuff). -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
