In the latest EAP's, it seems that key binding or something has changed. If I select a file in the Changes window, and get the diffs, so that it opens the diffs window, pressing Cmd-W (not sure if this happens on other platforms), winds up closing the last editor window behind it, not the actual diff window. This was not the case in RubyMine 3.0. I'm using the TextMate key bindings.
Are other people seeing this, is there a key-mapping change, or where is the key binding for this?
