As a "what the heck", I added myself as a Zolved.com guru, thinking I might be able to help one thing or another. I get notified of one to five questions per day posted.
The questions vary, but can be summed up thusly:
I just installed/upgraded Vista. I can't get __X__ to work.
Mostly, X is Mail from Yahoo and/or Earthlink or X is Sound. SOUND?
Well, to be fair, (or not), the Sound issue is likely either driver incompatibility or it's because Microsoft Vista *starts* with digital output, and there is a configuration change necessary to make the audio-out be analog.
I am not running Vista myself, but I may have to do so in order to support the legions of people who have done-it (in?) themselves. XP works, people. If you want Vista eyecandy on XP, there are ways to do it.
