There were a lot of issues that arose from trying to make GUI changes from another thread (even though we ran those functions in the right thread). Now we store layout information until the end of the load and make the changes then. This works much better from both a business logic and user experience perspective. Also prevents multiple sequences from taking focus during load and starting a render job.
