Has anything like this happened to anyone else? Cause I don't know and I'm not sure what happened... I'd thought maybe some folks here might be able to shed some light on it's possible causes? It's just it's a bit odd, cause it didn't affect any other application, other than those which used core-image... such as Photoshop & LightRoom. Initial Load After a restart! Don't worry though, I've managed to solved it. After a few restarts, deletion of the applications, associated prefs and support files.
