Closing Minecraft while talking crashes

[Fabian Maurer]

Closing Minecraft while talking crashes Minecraft:

java.lang.IllegalStateException: Interaction is not done yet. You have to cancel it to end it forcefully.

The window gets closed, but the process runs forever, until forcefully ended. For me it happens fairly often, so it keeps running in the background and I need to shut it down.

This is actually serious enough to make another release for 1.6.4. I also guess that this bug is still present in 0.4+

Cancel active interactions on shutting down the InteractionRegistry. Fixes #45
