Continuing support for Office 2004, the Microsoft Office 2004 11.5.8 Update addresses seven security vulnerabilities surrounding maliciously crafted Excel files that could enable an attacker to run arbitrary code and gain system user rights; accounts with administrative rights are at a greater risk than accounts with fewer privileges. The update addresses these issues by changing the way certain Excel files are parsed. It is rated Important for Microsoft Office 2004 for Mac and requires that you've previously installed the Microsoft Office 2004 for Mac 11.5.7 Update. The update is available from Microsoft's Web site and via the Office 2004 version of Microsoft AutoUpdate. (Free, 9.7 MB)
Close Word Comments Easily
If you don't like how precisely you must mouse in Microsoft Word 2008 to delete comment balloons, note that you can Control-click (right-click) a balloon to pop up a contextual menu. From the menu choose Delete Comment, and you're done.
Also, to get rid of all comments at once, choose Tools > Customize Keyboard and set up a keyboard shortcut to go with the DeleteAllComments command, available in the Tools category. Oddly, there's no Delete Comment keyboard customization option that I can find.
