With the recently released Project 2007 and Project Server 2007 Service Pack 2 (SP2) along with the Project 2007 and Project Server 2007 April Cumulative update hopefully we have seen the last of the false “check-in pending” issues. It is obviously still possible that the project may really be not checked in – but the false message should be a thing of the past. And I am absolutely positive that we you will tell me if I am wrong! And there could still be a scenario we haven’t heard about that we need to fix – so do let us know.
As with all cache related problems you may still see an issue if your cache is already “bad”, so best to make sure all your projects are really checked in on the server, and delete your cache (from the OS, not just the menu item in Pro) to ensure all is good when you load these new updates.
