We have several users (but not ALL users) that are unable to create a new timesheet within Project Server 2007. They receive the Yellow Triangle in the bottom left-hand side of Internet Explorer with the message ERROR ON PAGE when they attempt to do so. I have seen 2 different details when clicking on this error as follows:
1) Line: 1936
Error: Library not registered.
2) Line: 605
Error: 'g_oMainForm_name' is null or not an object
If they try on a different machine where the user is not experiencing the issue it works. Clearing the Internet Explorer cache is not working. I have yet to find any commonality among those that are experiencing the issue.
