Hi Frank,
The fact that the USB-mouse also gives problems is an indicator that light-pen is not at fault I think.
I suggest you join Facebook and become a member of Fairlight CMI group. This Yahoogroup is pretty low in activity.
Try reseating flatcables and card.
Regards,
Peter Kersten.

Subject: [Fairlight-CMI] Faulty light pen issue
Hey there everyone, just looking for some advice for a direction to proceed... Appears the light pen for my IIx is stuck in the HIT mode, only the issue is not in the actual pen but I believe somewhere else. Anyone experience something like this before? I can't get a cursor to display, adjusting the screen has no effect. Using the USB mouse adapter results in similar experience. Could there be a fault on a card? Hoping for some ideas. Thanks for your help in advance!
