I ran into this issue at a customer recently and thought I would share it on the blog in case someone else ran into. The customer is a heavy user of the document management solution TRIM and has the program TRIM Context installed on most of their PC’s in order to allow users to store documents directly in TRIM from their desktop applications. During user acceptance testing, one user was unable to save and publish their project schedules into Project Server in one session as the publish button was disabled until the schedule was saved, MS Project closed and the schedule reopened.
