--- Comment #18 from Zebediah Figura z.figura12@gmail.com --- The addition of flags 0xc000 means that WH_KEYBOARD_LL and WH_MOUSE_LL hooks were set.
Bizarrely, your log seems to only contain output from one thread in it, and I don't see any attempts to call hooks from that thread. I also don't see any +server output. Did you do any filtering of the log (besides just clipping it)? If +server doesn't work, can you try +msg instead?
My simplest guess is that somehow the game doesn't expect to receive some message until the hook is done executing, but I don't know what message that would be.
