Why do I get multiple points when I pass an object through a homemade photogate when using a homemade photogate adapter (HMP-BTD)?

If your HMP-BTD adapter was shipped prior to November 2000, you likely need a revised HMP-BTD. Please contact Vernier Software at (503) 277-2299 to exchange your adapter.

This problem seems to be more noticeable with newer/faster PC's. The extra points per pass, through the homemade photogate, can vary from 1 to 10 or more.
