Hi, I've just installed vista and i have this wonderfully strange problem.

outlook does not let me view or open attachments, get the error 'There was
an error saving one or more of the attachments"

Also, internet explorer will not save or open downloads, it downloads the
file, when i click either open or run, then when it finishes the download
window just closes, file doesn't get saved, although when i click run, i get
a comfirmation asking if i want to allow this file to berun click run and
nothing happens, highly annoying! cannot download an alternative browser
either which is even more annoying!!!
