HP Pavilion home edition pc purchased 8-08 with Vista OS installed. Everything running fine until January 09 when downloads began to disappear: meaning, I will attempt to download something, no error message is given, simply asked Save/Run, I click Save, and download apparently proceeds normally. But at the end, there is nothing there in the download folder.(This subject has been discussed before at ths forum I believe.) Techs have checked the machine, offered various theories. I just downloaded Vista SP2, which was thought would fix the problem, but it has not. Also have IE8 installed, same thing. I also have Firefox browser installed, and downloads disappear from that as well. Microsoft doesn’t even list this problem as a fixable thing Inability to download anything is a tremendous hardship in my work. Any help would be greatly appreciated! Pat Duke
