On Mac OS X Lion (10.7.5), Version 1.0.32 shows only a black screen,
in the console log, I get following errors (on an on, 4000 entries):
08.10.12 10:24:37,612 [0x0-0x88088].DefendersQuest: *** error: can't allocate region
08.10.12 10:24:37,612 [0x0-0x88088].DefendersQuest: *** set a breakpoint in malloc_error_break to debug
08.10.12 10:24:37,633 [0x0-0x88088].DefendersQuest: DefendersQuest(818,0xaca712c0) malloc: *** mmap(size=1925120) failed (error code=12)
It seems that the update from 1.0.1 to 1.0.32 did cause this issue,
when I go back to Version 1.0.1, I can play the game.
