GimmeSlack12 and other confused Mac-type people, I can explain the problem very thoroughly. I happen to be fixing a MacBook Pro, and even though I'm a Windows dude, I can at least describe the problem fairly accurately.
1) In Finder, click on Help -> Mac Help
2) When you are in a Help window, I believe what is being displayed are simple HTML or XML files, so when you first enter Help and see "What's New in Tiger?" etc., you are probably looking at an HTML file.
3) Under "Discovering Your Mac" click on "Work smart, play hard."
4) This is where the problem occurs. The "Discovering Your Mac" screen flickers over and over again. The problem is that the icon for "iTunes" next to the link "Inspire, Create, Enjoy" is NOT loading. I believe it is flickering because the Mac OS Finder recognizes that the image is not loading properly and thus attempts to reload the page over and over and over again. To be really thorough, instead of an iTunes icon, one would see an empty box of a question mark where the image should be.
5) I was able to fix this problem by running Software Update. Once I ran Software Update and applied the various updates including an iTunes update and went back into Help -> Mac Help -> "Work smart, play hard," the flicker stopped.
Finally, in addition to "Work smart, play hard," scribes mentions "Switching from Windows where are my applications." What is meant by that is again in Help -> Mac Help, there are links called "Switching from Windows," and then when that is clicked, there is another link called "Where are my applications?"
Granted, our level 1 walk-in techs should have caught the Software Updates first, but eh, whatever, it gave me something to do.
To the original poster, scribes, try running Software Update, and see if that fixes the problem. It did for me. If that doesn't work, run Disk Utility to repair permissions and repair the HDD, then see if the problem goes away.
scribes, I hope this Windows tech was able to properly diagnose and fix your Mac problem
