I have a same problem with Logos 1.2.1 in Snow Leopard 10.6.1.
I attached the screen shot for your information.
Yes. I have noticed the same thing. I am assuming it is due to the font chosen to display the parallel versions. However, there does not seem to be any option to change the font used.
The problem even affects the Spanish Bibles.
Read the blog post here. The bottom of the post in general is what you want to read.
alquien sabe cuanto tiempo mas para solucionar esto?
I've noticed some strange characters in the parallel bible and compare parallel bible tools. The bibles appear fine when I open them by themselves. Has anyone else noticed this issue?
