I operate MSOffice2003 on Windows XP; in Word2003 I, too, experience the obviously well known problem: in saving a document, when trying to open the pop-down menu SAVE IN, the sytem hangs and suddenly shows 100% system resources occupied. I (no longer) have any HP files showing in up in "Add/delete files", nor can I find the KB908531 security update that I saw someone refer to elsewhere. I have run ccleaner, RegistryBooster and what not, but the problem persists. Should I throw out anmd re-install the entire Office package, or does anyone have a aolution to come up with?
