Wayne,
Researching another issue, I stumbled across the reason for
your problem and suggest an easy fix.
In the output directory whgdata, these files;
whlstt0.htm, whlstt1.htm .... etc.
and
whlnvt30.htm
contain a line to set a value for "vertial"
alignment.
Make it "vertical."
I haven't had time to check RH project templates, so for now
I'm fixing it manually in output files.
Just last night I decided to report this as a bug.
