watchdog problem... solved?

Team 316 was having a problem with watchdog errors all build season and I think we just solved it. The problems were intermittent and most people on delphi suggested lengthening the watchdog time out. We found that moving the game adapter fixed our problem.

The watchdog is looking for communication from the driver station and if that is lost for longer than the watchdog timeout (default of 100ms) then the robot shuts down until coms are reestablished. I believe that the new game adapter's internal antannae is being blocked by the robot frame (similar to the recent iphone problems) and once we moved the game adapter so that the antannae is not blocked the problem immediately went away.
