Diffractor 122.7 can now be downloaded here.
It fixes a crash with various graphics cards that was affecting multiple users. If you are seeing crashes in Diffractor you should upgrade to this version. Sorry about the crashes folks :(
There has been a rationalization of keyboard accelerators. The biggest difference is a change in how SPACE and ENTER are used. SPACE now stops and starts video playback or slideshows. Enter opens items and toggles media full-screen. This makes Diffractor like most other Media software. Hopefully helps the transition for users between software products.
This release also includes a new Keyboard reference screen (control-F1) where accelerators can be reviewed.
