[plt-scheme] Never mind MrEd designer broken

Matthew---
        My bad, I realized that when I switched to v350 I had forgotten to
select the Graphical language level.  Once I do that it works fine.  The  
error message couldn't tell me that, but there's no reason to expect it   
could.

Thanks for wasting your time...
