Fixed point numbers are automatically converted to reals as required
in the SUN-only version of NeWS, but not in the "portable" version.
This is because whoever re-wrote the fixed-point arithmetic routines
in C rather than 68000 assembler decided that overflow checking wasn't
really necesary. The fix is not hard if you've got the source - I'll
mail it to you if you're interested.

Of course, if you're using the SUN-only version, I've mis-diagnosed
your problem.
