Hi Jan,
There have been several people (I'm one of them) who saw toolbar buttons
stop functioning and/or disappear when the tech refresh was installed.
John Carroll (another poster to this ng) and I were both instructed to:
Exit MS Project 2007
Delete the Global.MPT file
Restart Project to recreate the Global file.
This appeared to work for both John and I. I suggest trying the same.
If this does not resolve the issue, try posting the issue on the
Feedback site for MSP 2007 Beta:
http://connect.microsoft.com/feedback/SearchResults.aspx?FeedbackOverviewType=6&SiteID=235
You will need to login with a passport ID in order to post the feedback.
I hope this helps. Let us know how you get along.
