I installed Office 2004 on my MacBook, which already had Office X. This was some time ago, and Office 2004 has been running very well, faster in several key spreadsheets than X had been. IIRC, initially on occasion the wrong Office version would open, and also I had to take a look at the new preferences. I would suggest you ensure that 2004 opens instead of X, and also make sure the preferences are correct (that Office brought them over correctly). In some apps, with some preference settings, the last used directory is proposed for new opens and saves (instead of the default location). This may be not what you expect, especially when you first work with a document in Office 2004. Overall, Office 2004 works very well on MacBook, with 10.4.8.

Over the weekend we upgraded the office of a client from Office X running under OS X server 10.4.8 (with 10.4.8 on all clients) to Office 2004 and then patched up to the recent Office 11.3 release. The network is Cat 6 with Gigabit switches. Under Office X everything ran fine, now the users are getting intermittent errors: "There has been a network or file permission error. The network connection may be lost." The server icon remains on the desktop and files can be accessed. The current work around is to save the file to the desktop, quit Word and copy the file back to the correct position on the server. Any thoughts on what might be causing this? or should i think of backing out to Word X until the new version of Office or Leopard arrives?
