I am still using Office 2004 for the Mac and have not upgraded to the current version from Microsoft. In the time that I’ve been running Leopard as my Mac OS, I have noticed a general slowdown whenever I use Microsoft Word 2004. This fact seems to be borne out by the following error that appears in my Mac’s Console log:
2/12/08 12:23:18 PM [0x0-0xbb0bb].com.microsoft.Word Tue Feb 12 12:23:18 Macintosh.local Word <Error>: The function `CGPDFDocumentGetMediaBox’ is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance. Please use `CGPDFPageGetBoxRect’ instead.
