Yup, thanks to all who replied. I was trying to get things working a bit
at a time. ie. #1 -> draw the box, #2 -> process events for the box.

However #1 and #2 are a little more closely tied than that.

I have now the above code +
for (;;) {
  ModalDialog(NIL,&itemHit);
  process(itemHit);
}

and it all works nicely.
