I'm using OS X Snow Leopard with RubyMine 2.0. The renaming refactor no longer works on files in this release, but it works for directories. I find myself having to make a new copy of the file I want to rename and then deleting the old copy. Pretty annoying. Similarly, cut or copy followed by paste when trying to move files to a new directory often doesn't work on the first try. I usually have to go back to the files I want to cut or copy and try again. Second time is usually a success. This was true for RM 1.1.1 as well. Note that I get all of these problems using with the mouse, both an Apple Mighty Mouse and the touchpad on my MacBook.
Anyone else experience these issues?
