I've actually got an updated version of the Time Tracker app on my blog: http://www.ariankulp.com. I noticed that error too late. It should only bite you if you haven't set a project yet if I remember right. My new version remembers the last project you selected as has a number of other enhancements too. The direct blog entry for getting the code or installing (slick ClickOnce installer now!) is at: http://ariankulp.com/archive/2005/11/26/666.aspx.
