BLACK SCREEN

[dpel]

All of a sudden my display blacks out.
I can still see and use the mouse. I can COMMAND TAB between applications
and see them but when I select Live the display goes black again.

Then Live finally crashes.

btw, i leave the computer on with a session loaded in Live overnight.
This shouldn't be an issue though.

Live 6.01 and Reason 3.5
