Background Information
In the Project Center page in Project Web App (PWA), the names of projects and their Gantt bars are misaligned by one row. When you click the name of any project in the Project Center page to display a Project Details view of the project, the task names and Gantt bars are also misaligned by one row.
Resolution
This problem is caused entirely by changing the Zoom level in the Internet Explorer, and not by any bug in Project Server 2010. Click the Zoom pickl list button in the lower right corner of the Internet Explorer application window and set the Zoom level to 100%.
