- Electron version: 1.1.2 arch=ia32
- Operating system: Windows 7x64

Electron is using the largest icon available in the .ico file for the windows bar.  I set the icon in my main window with `createWindow('main', { ...icon: icon_path })`

You can reproduce this with an icon that displays the size: (click 'test icon with several images' to download)

here is a screenshot of the wrong icon being used (should be 32x icon):
