Err ... sorry, but I'm having problems because Vista still has crap hardware support (particularly for older hardware) has been rushed out while still full of bugs, is generally flakey and in a lot of cases, doesn't behave logically. Try opening your own document folder for instance from My Computer or Explorer - you'll find you're denied access and to get access is an unbelievably fiddly and complex business. Of course you can access your documents without taking ownership and setting complex NTFS permissions, but it's not by the most obvious path, and there seems no good reason to deny access to My Documents by whatever route is chosen.

And just for the record, I installed Vista onto a "clean machine", ie I formatted the hard drive it was being installed onto - I also had to reinstall XP on the other hard drive (thanks to Vista) so really nothing was cluttered or pre-configured. I'm not the only person to be having Vista frustrations - it's just Vista, not me.
