at the top of iTunes, its suppose to display the words artist, album etc. and if you hit them then it will sort by whatever you hit. The problem is that the words are unclear. Any ideas why that is?
By "words are unclear" I'm assuming that you mean illegible. Illegible words in standard OS X apps are usually caused by font problems. If you have a ton of fonts loaded on your system one or more could be causing a conflict with a system font (usually Helvetica, I've found) Use Font Book (if you don't have a better, 3rd party font manager) to resolve duplicates, or follow Extensis' "Best font management in OS X" white paper (go to http://extensis.com)
If this doesn't address your problem, please clarify what the issue is so we can better assist you.
