MSNTV with the latest upgrade has managed to depreciate the usage of css once again.The changes in link color is the result of css link colors no longer working--- a:link and a:visited link no longer works in external or internal style sheets so nope we`re not getting closer to seeing what pc`s see instead we`re getting further away from what they see.
The new link colors that you`re seeing are the msntv default colors,they may look slightly different on different colored backgrounds but they are the default colors you`re seeing.
