I'm having trouble with Photoshop...

Really? Works fine with me, and I'm running Ultimate. I've got a number of friends who do Art and thus use Photoshop CS3, all of them run different flavours of Vista, and they've got no problems. So I could, by the same logic, guarantee that is is NOT Vista that is causing the minor inconvenience. Not that it helps any more than saying it is, mind.

How can it not be Vista, I have a running XP with the same everything and Photoshop opens everything much faster and doesn't have the wait time that the Vista does.

Of course let me state that it wasn't always this way, Vista used to open it up in the past when it was new. It seems that one of the updates for the system has screwed it up.

I say stay away from the Windows Vista Updates if you know what's good for you.

OR

Just downgrade to an XP and make sure to look around for the bios etc before doing so that way nothing goes wrong when you do it. Also make sure not to change your computers SSID in fear of making backup discs with another SSID and then the recovery discs won't work.
