files lost in Vista somewhere? files disappear into oblivion after saving and closing?
you are probably a victim of Filesystem Virtualization, a feature of the UAC. Use the latest vista-aware versions of your application wherever possible. try to not save into protected directories such as
C:\Program Files. If you have an older program that does this, like a game, you may have a problem. Writes to
C:\Program Files end up at
C:\Users\yourusername\AppData\Local\VirtualStore\Program Files\ if yours is a non-vista app.
