Projects show checked out but aren't really open.

Occasionally a project will show checked out in the project view but the file
is not open by anyone. We are using Project 2003.

The manager of the checked out project can check it in him/herself by
navigating to the Project Center page and clicking the "Check in my
projects" link in the sidepane on the left. The Project Server
administrator can also check in the checked out project using the steps
detailed in the following link:

Hope this helps.
