Hmm. Thank you for the response. =)
Unforunately, I'been told this answer, and I find it an unacceptable one. My company runs reports, including year-end reports, on the estimated and actual hours of these projects. Deleting them would defeat the purpose of having them all in a database.
I have found the ability to view only open tasks in the timesheet, but that eliminates the Non-Working Hours Project from view as well.
Does anyone else have experience with this?
