I'm running Aleph 1.0.1 on a Mac Pro 5.1, OS 10.6.8. I have a "Logitech Illuminated Ultrathin Wired Keyboard with Backlighting" and I am unable to use the Number Lock key in-game (located in its standard position above the "7" on the keypad). In the Aleph Marathon preference panel I can successfully assign the key (I want to use it for "Previous Weapon") however while playing the game it will not work at all.
Also I tried to view the guide for submitting bugs but got an error message.
I see the same problem here, on my MacBook Air with Lion. I'll look into it, thanks.
Thanks also for the note about the bug guide; the link is fixed now.
