Microsoft just released a new update for Microsoft Office 2008 for Mac which included numerous fixes to stability & performance. This is almost a mandatory update as it addresses significant bugs in almost all Office components.
Users experiencing crashes in all Office applications will be glad to know that this has been fixed across the board and Microsoft has also fixed a date issue in charts displayed in Word & PowerPoint.
Six issue areas were corrected or improved in Word 2008 specifically, many of which are conversion-related (between various Word versions) and one involved a macro-glitch may have had a nasty impact in a multi-platform shop (as it lay waste to VBA macros in some circumstances).
Eight groups of issues in Excel 2008 have been addressed including a formula bug that you may not have even noticed (formulas were not executed properly under a few scenarios). PowerPoint 2008 is not nearly as sluggish as it has been and you can more confidently sleep/wake your Mac with Entourage 2008 running.
