I have a stable fast install of Vista. I find it loads btter than xp, dx10 is great & I would not go back.
I really don't see that those working in a dos database environment are entitled to coplain about Vista - it wasn't made with that in mind. Those people should content themselves with 3.1.
Most problems that I see are caused by software & hardware vendors rather than MS itself, after all, vista was in development for five plus years - the 3rd party community are a little disingenous to come out & say they don't have compatible software, drivers etc when they've had plenty of time to patch/update theur products.
Fargoo, go to user accounts & switch off user account control & your vista experience will improve no end.
