Trouble Shutting down

[Juan Ortega]

I'm using FreeBSD amd64  8-0-Current

I set up window maker to start by "startx" command,
but when I exit the window maker the screen just turns
black nothing works so I'm force to unplug the power each
time. This happens "sometimes" other times the terminal
shows up and I can shutdown manually. Since I'm using
a snapshot version of FreeBSD is this a bug?

I'm not sure what logs to copy and paste here for more information.
