Hello
I heard that windows vista has problems with some programs.
Is anyone using Ps cs2 with vista?

The only problem I had with CS2 on Vista was the annoying "Register now" popup.  After I ran PS by right-clicking on the icon and choosing "Run as Administrator" it was able to stop that.  Also had to do this so a couple of my plugins would accept their registration codes.  Other than that, no major problems.  It's since been upgraded to CS3 which went without a problem.

Oops I have just realised that this thread should not be here in the video section...

Will you recommend to install Vista or XP in a new computer?

How new of a computer?  Did you build it yourself, or is it a pre-assembled one?  Is it a desktop or laptop, and how much memory?

My laptop runs vista (in 32-bit mode)...it drives me up a wall when the hard drive starts running for no reason--even after getting the memory up to 3GB.  My wife runs the 64-bit version of Vista on a machine I built last year--4GB of memory, dedicated hard drives & such.  Vista doesn't bother her at all.  At my day job, the machine I use runs XP.

At some point MS is going to stop supporting XP, and then you'll have to decide on whether to just keep running, or upgrade to whatever the latest version of Windows is.  Or you can avoid a future OS reload (and PS with all your plugins, etc) by going with Vista now.  But it'll drive you bats with how much memory it consumes just to present you with a UI, and by how often the hard drive just mysteriously becomes busy.

At least PS runs fine.   

It will be custom built. Desktop. No less than 4gb of memory.
the guy in the shop recommended me to install XP but  perhaps you are right about XP having a short future...

XP is certainly fully capable and uses less system resources than Vista, just know that you'll have to run a 64-bit version of either OS to see your 4th+ GB of memory..  Since your machine will be new there should be pretty good driver support for Vista.  It was a bit tricky over a year ago building a Vista machine as several components didn't have drivers available yet.  I think one of the last drivers I had to wait for were Epson's 64-bit drivers for the R2400.
