Today I was able to successfully finally start trying to load my day-to-day applications in Vista and see how well they run.
So far, nothing stands out as application that is struggling to adapt. Adobe Photoshop CS works fine, as does the Office 2003 suite.
But I did notice something weird when I installed iTunes. Whenever iTunes 4.9 is running, it shuts down the Aero Glass effects. My screen will flicker once the application is started and poof, no glass or transparencies. Now once iTunes has been exited, the Aero glass effects come back.
Weird huh? Not a big problem to me, because the application still works and does what I need it to do - play music.
