Try putting a cardboard toilet paper tube over the dinky link and point it so the neon is not hitting the dinky link. If the problem goes away it is an ir problem and you can try relocating the dinky link or use a micro link - it can be recessed and made more directional, if it is an rf problem the cardboard tube will not help, shielded cable may be the answer. Of course it could be both.
I like the idea of using X10 to turn off the light when using the system but won't the neon keep the remote from operating to turn it off?
