My PZ-1p, 37, occasionally 38. Wife's Canon, always 36 (they seem to have
designed the film transport to do that on purpose). My manual load cameras,
36-37 full frames and some partials.
I can see the advantage of Canon's solution, and would prefer it as it
saves the pictuers I've already taken. However, I solved the problem by
learning how to check for film in the cameras and training myself to always
check before opening. Haven't had the problem in years.
However, if that is such a problem, then why hasn't some company designed
an interlock to prevent the camera back from being opened when there is film
in it?

Perhaps patent infringement?

Sounds like you pulled out too much film while loading. I used to do that
sometimes while I was learning to use my K-1000 or having a fit loading it.
