So for the past few months my instant messenger is being stupid. When i direct connect with someone i am not able to view any pictures they send me. It comes up as a blank white spot. I can't even see smiley faces....they come up as a box with a red X in it. Ive tried everything imaginable....ive upgraded and everything and still it doesnt work. Any idea on what to do ?....the firewall thingamajig is right where it should be.
