I have recently installed Windows 7 on my Sony Vaio VGN-FE21M. All works fine, except when I connect my laptop on my docking station VGP-PRFE1. The audio port does not function and also the DVI and VGA video ports are very unstable. I don't see any specific software for the docking station I can download, but possibly I have to download other software to make the docking station compatible with Windows 7. Please advise.
