Hi,
Could it be that the keyboard is too close to the A4000 video port ? Therefore if the VGA adaptor is too bulk it presses against the keyboard lead - could damage the socket.
I found the DCE external flicker fixer had this problem, it could just about squeeze in, but with the pressure on the keyboard connector I bet it would damage the socket long term - swapped it for an internal one. One Australian(?) company I noticed doesn't recommend the external DCE flicker fixers for A4000's, so the question is how bulky is the eyetech adaptor ? (if they've used a standard hobby electronics box it could explain it)
