Is anyone using CS3 with VISTA 64 bit? If so are you having any difficulties?

We have CS3 on our desktops at work. This month VISTA 64 bit is going to be installed on our desktops.

I was wondering if I should expect difficulties and if so how to avoid them. I just hate this "modernization stuff. I have my work station working and want to keep it that way but I have to make room for progress.
