I ran the Safari 4.0 update and restarted my iBook G4. Now the display is slightly larger than my actual screen size, and the graphics quality is worse -- everything appears slightly out of focus. As I move the mouse around, the display moves also; for example, if I move the mouse to the upper left, the Apple menu icon comes into view, but I can't see the dock on the right, and if I move the mouse to the right, the dock comes into view, but the Apple menu moves beyond the edge of the screen. It's about to give me a headache. I went into the Displays menu; I'm set at 1024x768, and my only other options are 640x480 and 800x600, neither of which helps. This computer is 4 or 5 years old, and this problem is new. Yes, I restarted -- no change. (The old display proportions appear for a moment during start-up, but then the new display takes over.) What has happened, and how do I get my old display proportions back?
