Also DrRacket doesn’t seem to want to quit.  I click on the quit option in the 
menu, it asks me if I really want to quit, I say I do, and then it closes the 
window, but doesn’t quit the application. I tell it to quit again, nothing 
happens, and then if I tell my computer to force quit DrRacket, then it comes 
up with a DrRacket internal error box and then almost immediately after that 
another little window asking me if I really want to quit, and then a second or 
so later my computer forces DrRacket to quit and both of those are gone.
This happened three times, and the third time I took a video of it, and with 
that I managed to read the internal error box:
terminate break
  context:
    /Applications/Racket/April-24/Racket
v6.2.0.2/collects/racket/private/misc.rkt:168:2: channel-put
    /Applications/Racket/April-24/Racket

No more of it is shown in the box in the video I took, and couldn’t scroll down 
to read the rest of it because my computer forced DrRacket to quit right 
afterwards.  

If I turn the racketeer tool off it quits normally.
