   Scheme GUI questions.
  I'm using PLT-Scheme and trying to learn the scheme/gui lib. One thing I've noticed is that Window controls -- textfields, radio buttons, etc. -- can be given labels. However, I can't find any way to actually set a label's position. I'd like them to go above the associated control, but they end up either on the left or right (and I can't control whether it's to the left or right, for that matter). Anyone know how to do this, if it's even possible?   
  IIRC, some gui controls have a "vertical" style that will do this -- but in any case it is much better to ask on the plt scheme mailing list.
