[plt-scheme] Problem with call/cc and multiple values

I'm using DrScheme 4.1.3. Here's the problem:

     > (values 1 2)
     1
     2
     > (let/cc return
         (return (values 1 2)))
     . . context expected 1 value, received 2 values: 1 2

The context is definitely not expecting one value. call/cc and let/ec 
also give this error. I think it's supposed to work, though. From the docs:

     "The arguments supplied to an applied procedure become
     the result values for the restored continuation. In
     particular, if multiple arguments are supplied, then the
     continuation receives multiple results."
