For the life of me, I am almost unable to resize the iTunes window (with visual effects OFF no less)! Its window UI is almost unresponsive. Menus and native-windows-looking alerts are responsive and fast, however the metal interface is just unusable here. I can’t easily resize the application, and with difficulty I can scroll the scrollbars in the store or the Library! After many attempts, I managed to get the window size down to about 640×480 and then the application did become more responsive and workable.
But on a normal ~1024×1000 window, it is just unusable. There are times I can’t even move the whole window across the screen! Note: I am not talking about playback (which works fine with no performance issues), or when in mini-mode: I am talking about scrolling/resizing the app when the window is in normal mode and bigger than 800×600. Resizing the window when in “Music Store” is almost impossible here! Update: Upgrading to the latest graphics drivers didn’t help.
