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.








Thanks, Joey. Just got Joost installed today and that same problem promptly occurred. I ran it as a local user, and now it works. If you find a permanent fix, be sure to post it!
Hi Randy,
I’m sure the problem will be fixed once Joost is closer to a final release. I’ve never come across another application that wouldn’t run as a Domain user before. It’s not a permissions thing as I have full admin rights on my laptop, and I’m a Domain Admin anyway! Plus, it runs fine as a Domain user on other machines so it’s just something specific to certain Dell models!
