The light leak is where the dark slide goes in the holder this can be a problem on any size holder. Best to lay the dark slide or drape the dark cloth over the top when doing vertical with the light source over head.
Richard,

I am pleased to hear that some standards are being agreed between manufacturers. Its pretty frustrating otherwise for the end user.

In my case I have a modern camera with modern film holders. I must say though that I am not entirely happy with my film holders dimensionally, even though one holder manufacturer had a camera back to use for dimensioning. They work but they could be much better.
