Known Issues with 1.4.21

• (Microsoft Windows version): As of 1.4.18, running aven creates an extra empty window which seems to stay open until aven is closed (#146). Aven's main window opens in front of this useless window so it doesn't really get in the way but it shouldn't be there. We attempted a fix in 1.4.21 but reportedly it hasn't worked. If you're familiar with development on this platform and think you may be able to help fix this, please get in touch!
