When you type something in spotlight, highlight a result and hit Command+Enter, it should open the containing folder in finder (For reference). However, it does not work on my OSX 10.8.2 MBPR. The finder application comes to the foreground (the finder menu bar is shown on top of the screen), but no finder window on the location gets opened.
I have BetterTouchTool installed and thought this could cause it somehow, but, having it deactivated, keeps happening.
