Revised: This was solved for me by using the curse client to uninstall Carbonite including all setting. Manually checking that all of the folders and settings were deleted and then reinstalling directly from the download page. I have played 3 characters up to now all Carbonite is working on all three.
This is the same for me whether I use the release version or any version up to and including the last alpha release. The quest log is usable but need to do a log of scrolling as you can see by the graphics.
I am not a lua programmer but I can imagine what you addon authors must go through with us nit picking your addon. I just want to say that you guys are fantastic and keep up the good work.
