Well, I tried it on my xp sp3 machine and it just locks up. I was able to add my library and then view it. I tried to open a book and it just froze. It finally lets loose and goes back to the library listings. I tried half a dozen times and it just wouldn't work. It also took forever to load the software. I watched the hd light working like crazy to get it to load. It was using 99% resources and I had nothing else running. My system is a few years old, but its got a 2.41 ghz processor and 3 gigs of ram on a Asus mobo. I'll try it later after a lot of the bugs and complaints are fixed. The only new thing I saw was notes, so I just uninstalled, removed the kinoma and sony files and reinstalled the old stuff. Reloaded my library and it works like it should. The software leaves a lot to be desired and I was hoping Sony had listened to our emails, but the new one is just as bad as the old one. Oh, except I can get the old one to work.

That was a wasted hour. Now to go try it out on the mac mini
