I am using Microsoft Office for Mac 2008, which has been performing fine for many months. Now all of a sudden the icons are missing on my toolbars. All that it shows in the toolbar window, (both standard and format toolbars), is the text without the icons, with just a blank dark area where the tool icons should be, leaving the toolbar impossible to use in any practical way. No amount of selecting or de-selecting the toolbars via drop down window "view", or changing the option for "text and icons", or "resetting the toolbars in customise will change this situation. The problem has occurred in all of "word", "excel", "PowerPoint" and Entourage. I have tried reinstalling office from the original CD, but the problem persists. I have even quarantined the normal.dotm file before reinstalling office, but it simply created a new "normal" file with the same result. No icons on the toolbars. I am using OS X leopard. I haven't yet resorted to reinstalling leopard, but what else is there?!? Any clues to what has caused this to suddenly occur?
