I have been able to refactor my class names with: RBClassRegexRefactoring new renameClasses; replace: '^XXX(.*)$' with: 'YY$1' ignoreCase: false; execute But since then, Nautilus looks like quite lost with a number of weird behaviors. Is there a way to reset Nautilus after such refactorings? I suspect that there is a cache somewhere that begs to be rebuilt... Phil
