This was not an issue in CodeRush, just CodeRush for Roslyn.
When I use CamelCaseRight on a line that is wider than the code window, the caret will continue moving to the right but the window does not scroll (horizontally) to keep the caret in view.
Hello,

I have reproduced this behavior locally. We are working on a solution, you will be notified when a fix is ready.
