In case anybody ever digs more deeply into Dialedit, I've got dialogs 
working fairly well by making sure that LineEdit controls have strings 
that are multiple of 8 bytes (i.e. lengths 15, 31 and so on). 
RadioButtons values appear to be a byte, CheckBoxes possibly a word. 
Working on ARM, i386, x86_64; part-working on SPARC which I think 
indicates an endianness issue somewhere, untested on PPC and MIPS.
