In Windows Help, do a search for XP Compatability Mode.
You should be able to set Envisage to run under this mode, and all will be good. (fingers crossed

) You need to log on as Administrator to make the change.
BTW, when I first started using my LPI I had to reload the drivers each time I wanted to use the camera. After about the 5th time it started working fine.

Had no problems since.
