I'm currently running Vista SP2 on my laptop and have encountered problems opening and saving in most programs. when I try attaching files in emails and click browse, a window quickly appears and closes before I can do anything. I've tried switching browsers (IE, Firefox, Safari) all with the same result. I've reinstalled them with no difference. In other programs, like word, Photoshop etc, I'lll go to file > open as/save as and nothing happens. The dialog box only seems to work in notepad.
I searched around a bit on here and google without much luck. Any help would be really appreciated. thanks in advance.
