What about compatibility with the coming Yosemite?
I have been running the latest Yosemite as I do some dev work for internal projects where I work. However, I just got a rush job for FotoMagico, haven’t used it since upgrading to Yosemite, and it isn’t looking good. The slide preview views are shifted out of place. 
Sorry, didn’t realize this was for Mouseposé. This forum is a bit unlike others, so my apologies.
