I'm new to RubyMine and having trouble with renaming methods. If I select a symbol and press Shift+F6, nothing happens. If I right click and select Refactor-Rename, I get a dialog with "Rename method xxx of class Yyy and its usages to:" and the suggested renaming (actually just the same as the original). If I enter a new name and click "Refactor," nothing at all happens. This is true whether or not I check the "Search in comments and strings" boxes. I don't know if there is a problem with my installation or what. I'm using RubyMine 4.5.4 on Ubuntu 12.04. Thanks for any help.
