Just recently, I got my hands on a new Dell Latitude D820 laptop and it took me a few days to get everything migrated from my old laptop. Everything was running fine, including Joost, until that is, I joined my machine to our Active Directory domain at work. Every time I attempted to start Joost, tvprunner.exe would crash with the error: “The exception Breakpoint. A breakpoint has been reached.”
I tried deleting Application Data\Joost and Local Settings\Application Data\Joost but to no avail. I then tried running Joost as another domain user but the same error appeared. What I then tried was logging in as a local user, created during the initial XP install and low and behold, Joost ran just fine. I now just use “Run as…” and use a local account to launch Joost when logged in as a domain user.
This problem seems to be widespread on certain Dell machines, notably on Latitude D820s, three of which I tried myself and others which have also been reported on the Joost forum. However it runs fine as a domain user on both my Dell Precision desktop in work and a Dell XPS laptop I tested on. I haven’t had a chance to try Joost on a non-Dell build of XP on a Latitude yet to figure out if it’s something with the Dell supplied install of XP. Both the Precision desktop and XPS laptop were running standard builds.
