1.The Taskbar was never locked
2. I did not mess with my settings, the new iTunes update was the source of problems.
3.I got everything, and that was only the location of the Quick Launch toolbar, and the minimized link to the opened page, or whatever it is called. I was able to accomplish the reversal, just as Don described (but honestly, I did it before seeing the post.
4. I am not sure what is normal, since I have recollection of what I did. Is the Tasker supposed to be "hidden" when a program is in use, and it is maximized. I, just don't remember.
5. James, if you have no suggestion, please keep your opinions to yourself. I never made a change in settings, when something odd happened. You know, well, that to use a computer can lead to many problems, just using the mouse.
I have had this computer for nearly four years, and the first problem happened when I tried to update to SP3. That problem was solved. It happened to others.
The second problem happened after iTunes failed to update, and it rolled back to the previous version. Many others had the same problem.
