Vision tracking issues

[avestasticc]

We have tried vision tracking with an axis camera as well as USB. We switched to a USB camera, a Microsoft life cam. We program with labview. We have had troubles connecting to the field at the competitions we have been to. It would work everywhere else but the competition field. We have found that the problem is that the vision tracking won't work unless its running from robot main. We are getting feed to the dash without lag tethered and untethered. We had talked to everyone we could at this regional, yet no one knew what was happening. National jnstruments was contacted as well but they said everything should be working. We figured it might not be the code since the code works very well from robot main. Everything is set to get the IP from the field. We tested with static, but it also did not work. At this point we don't know what the problem could be, and any help would be greatly appreciated.
