osx external mouse right click

[antgeth]

after several years of playing i've finally convinced my partner to try out the game (hooray!).  she's running it on her mid-2012 13" macbook pro under 10.9.5.  for whatever reason, right clicks on an external mouse are rarely recognised in-game.  it's not the mouse itself -- it works perfectly in any other program.  likewise, it's not just ksp; right clicks using the trackpad work just fine.  but 98% of the time she right clicks on the mouse, the game doesn't see it.  any solutions/explanations/etc for this? it's really strange.

This thread might have some useful information for you - It's nearly as old as that laptop:

Otherwise I'm stumped sorry
