Here is a little well problem I have come across in Vista. I really like the mail and web apps from Mozilla (Firefox and Thunderbird) especially as they keep them selves up to date with there own on-line update system. Only in vista they have kept telling me I need to update and when I go through the motions it doesn’t update??
This is because the software needs to run with admin rights to perform the update. It does not check however when doing an on-line update or try to gain the elevated rights. To make it install for the time being you need to right click on a short cut to the app or the exe itself and select to run as administrator. Problem solved until Mozilla get Vista compliant.
