I'm sorry for the untelligibility of my post. In facts I can open office, but in the file I just can see pictures or lay-out, but the writings are missing.
If I send the files to another Mac it's readable (normal)
If I print it from my computer... all writings are missing.
I just noticed that If I try to sava as with a new name, I can't see while typing the new name either, which can be seen onve saved.
Furthermore when switching from one ope soft to another with the shortcut (apple + tab) I see the icons but not the names of the applications)
Strange!
Do you know what it can be?
One more information. Everything has changed after installing the Security update 2008-004 (Power PC) and Safari 3.1.2
