A strange problem began occurring after applying MOSS2 (KB953334) and the August 2009 cumulative update to our Project server.
When a user enters the 'Task Update' screen they are prompted to download a new ActiveX control. Upon refresh, and subsequent access attempts, the user is presented with a blank grid with the caption 'Loading Grid...'
We have attempted to fix this issue by updating the 'Trusted Sites' list and changing the security settings according to KB818046. However, nothing seems to definitely fix the problem.
Also, when the problem randomly fixes itself, it still occurs when viewing specific projects.
Any ideas on a fix?
