[JosAH]

The following code is not working.it gives the same error messege as it gives when program specified for win95/98 is run.

Too bad; sadly enough we're not all psychic so could you please elaborate a bit
on *what* the error is exactly? And *what* did you expect it to do? Please help
us to help you.

kind regards,

Jos

ps. I also changed your topic title ("hi" was not a very informative title)
