title: MacVim on OSX / Yosemite: no editor windows visible at all
body: <p>Installed MacVim on my Yosemite 10.10.2 Macbook Pro today from <a href="http://www.macupdate.com/app/mac/25988/macvim" rel="noreferrer">http://www.macupdate.com/app/mac/25988/macvim</a></p>
  
  <p>The problem is that no editor window(s) are visible.  If I open a file using the menu, there's simply no effect: no editor window appears.  It's not hidden behind other windows, it's not listed in the Windows menu, it's just entirely undisplayed.</p>
  
  <p>Strangely, the file will appear in the MRU list, though.   So this renders the entire editor completely useless.   Should I just build gvim myself?  Is this app actually being maintained by anyone?</p>
