Indeed, we just hit that problem at my work - the way it `works' in windows is exactly this: it constantly polls the card at a certain interval, even plain USB drives are polled. And with our windows product installed, from times to times something happens that causes windows to think that the card has been'removed' although it hasn't been touched - bleach! -- Greetings, Andrew ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
