Hello everybody, I am new on this forum and I wish I could get some useful advices from those of you what they have experieced already Windows Vista.Its wonderful, I like it, but I find it sometimes boring with all its new things, I am too much addicted and used to XP. Regarding Vista, I encounterd a problem. The problem is that these programs of messenger are not working at all, programs such as Yahoo, MSN, or Skype do not work.I had installed them an reinstalled and nothing, Yahoo messenger it works sometimes and that times is disconnecting very often only in case that in connection preferences box of yahoo, I chose firewall with no proxy. Do any of you encounterd his kind of problem. It might be a problem of antivirus, of windows firewall. I use AVG free trial antivirus. Could any of you help me in solving this problem, even if I have a very performant computer, I can not use it for internet communication, which is very important for me. Thanks! Mario.
