I have custom columns but not based on others. No tag browser, no color rules ..
I have never been able to find out why I have these problems and by now I just live with it.
I will check the thread you linked.
Did I get you right, instead of simply upgrading you suggest I should keep the library (the actual book files folder), uninstall and/or install calibre as new?
