The record that Dialedit generates to represent initial or extracted 
dialogue box values has alignment and/or packing problems. There's a 
comment in the source that the FreeVision sources expect dwords while 
the author using a debugger believed that words were correct.

I was able to get things working adequately by assuming that the correct 
type for a RadioButton was a byte, and that the CheckBoxes the followed 
it were..., well something larger but I'm still not sure what.
