Reactivision detecting Fiducials that are not there..

[dotbond]

Hi, we are using Reactivision 1.4 on a Windows XP Pro SP3 machine using a basic Logitech camera. We have a random problem where the program is detecting TUIO Fudicials when there are not being detected by the camera, i.e. there are not any objects in front of the camera.

Anybody come across this problem before?

Thanks
