Beware -over the past couple of weeks I have updated a couple of older iMac 17 PPC machines and have found that the non-admin user on those cpus can be affected by Word crashing or just the spinning wheel of death - would post more but VT wants copy in 45 seconds

Note that Microsoft has done a good job with support up until 11.5.3 & along with Open XML Converter is a reasonable solutions - but Office 2008 is very pricey, and may not make sense especially when NeoOffice and Apple's iWork are very good alternative products.

Please note that I have been using Microsoft products since 1989.
