Viewing Slideshow in Bridge CS6 causes Black Screen

Question

Not a question, just an observation that I don't know where else to report this.
I was using Bridge CS6 to view a folder of 200+ photos in Slideshow mode (Ctrl + L).
I was simply using the left and right arrow, occassionally the Spacebar, and marking about 25% of them as rejects by using the keyboard shortcut Alt + Delete.
Suddenly the entire monitor went black. No text message (not the Black Screen of Death), just black. I tried several standard Windows keyboard shortcuts to try to get a different view (Windows + Tab, Ctrl + Alt + Delete, etc.), but nothing worked. I could tell that the monitor was still functioning correctly by simply bringing up its on-screen menues. The only thing that I could do was to turn off the power to the computer. After rebooting, Windows, Photoshop, and Bridge all seemed to operate correctly (but I haven't yet gone back to Slideshow view).
I haven't had a program or Windows crash for months now, but I just installed Photoshop CS6 (not the extended version) late last week.

Answer 1

I can't help with the black screen, but that sounds like a slightly risky way of cleaning out the rejects.  I prefer to give non keepers a single star (Ctrl 1) and bring them up with the filters, so I can look through them one last time. 
Just a thought, but there is a tenuous link with slide shows and projectors.  I wonder if it went into external monitor only mode.  (Windows key p)   I have just tried it here, and was unable to make anything appear on my main screen.  You'd be working blind, but a possible solution (if it happened again) would be to go Windows key p  > right cursor key (once) > Enter.   That would put you back into main monitor only mode.
