Shift+O Force Closing Game Client

As stated in the thread title, my game force closes after hitting the aforementioned key combo. I'll list below what I think are a few notable pieces of information on the matter:
• Using 64-bit client
• "Input" is set to default
• Shift+O isn't closing any other applications on my computer
• Shift+O only force closes POE client when it's keyed in-game (minimizing the game & hitting the key combo @ the desktop does not close it)

It's not a huge deal, as it's quite easy to work around this issue. But I was curious to know if anyone else was experiencing this as well.
