[BUG] exposé + cmd = Unknown modifier with keycode: 0

[Obsyd]

Hello there!

If I fire up the exposé view in osx (10.9) and hold down cmd and select my lwjgl window (while holding down cmd) the Unknown modifier with keycode: 0 message appears.

I'm on a hackintosh, if that matters. (have a large apple keyboard)

Thank you!

Ohh, and I'm using the latest Nightly build.
