It's what Windows reports to us. If I remember correctly Windows does something wierd here. If you set your machine to "small fonts" then it assumes one value for pixels-per-inch. If you set it to "large fonts" then it assumes another value. Neither of them may be the actually PPI of your screen. I think it has to be done this way for back compatibility. BR, Robert Thorpe
