Dialog box unresponsive when attempting to move files since 8.0.2

I'm having an issue when attempting to move files using drag and drop in RubyMine.  The confirmation dialog is displayed with the correct information, but doesn't respond to mouse events, just the keyboard.  Not a big problem - I can always use Finder as a workaround.

Mac OS X 10.11.1, RubyMine 8.0.2
