MineMenu 1.8.7

Selecting an unbound keybind currently means that every time that menu entry is selected, ALL unbound keybindings are activated at once.

There's nothing in the logs to show, and no crash occurs, however, if you still wish for me to post the logs let me know!

P.S. Unrelated but does MineMenu support some of the more 'out there' MC-supported keybindings such as F13-F25?

Nothing that can be done about that, that's just how vanilla treats it.

That's a shame, but I understand!

Just thinking outside the box real quick - is there no way to direct the keypress event to only the specific mod being targeted? I'm not a Java / FML expert, I'm not sure what the limitations are...
