When import a CF 1080p file into a Red 1K PPro CS5 project, all changes I make in Firstlight appear in the source monitor, and also in the Program monitor when I bring the clip to a RED 1K sequence. But as soon as select "Scale to frame size" with a right click to view the 1080p file properly in the 1K monitor, all the settings made in Firstlight disappear from the Program monitor. Any idea why?

Software: Windows 7, Neo 4K

I just tried that and it worked fine here. I can't think of how it would fail, are you sure you are not just seeing cached frames?
