Thanks for the sarcasm. I'm not exactly sure what "it's my most probably my.." means, but I get your point. Maybe I should point out that all users are on SP3, that I cannot create the error, and that it goes away when they reinstall windows. I must admit the whole object reference thread was a bit beyond me. I don't think I even have properties that reference external objects. Regardless, why would my dirty object references work and then not work and then work again?
It would make a little sense if more than one person could do the same thing and get the same result, C5 fatal error.

Marcus.
