With the new look previewer I have had to abandon any testing what so ever. When it was just Dazzle I had so many crashing issues that I was unable to log in at all with out it crashing on start up. I did a cold reboot and the problem would ease right back.
Then Dazzle became First Look Viewer and I couldn't login with out it crashing as soon as I hit the logo to login and was forced to abandon the viewer.
I have Pentium Duo Core HP Laptop, nVidia GEFORCE GO 7400 graphics card and 2 GIGS of memory and I am still running windows XP.
