Hi Stu,
     I did understand your question 100 percent. The IDV need to fix this 
problem later. But you can have a work around here at this moment. I would 
suggest you to combine these two lines as:

<viewpoint scale="0.4" aspectx="1" aspecty="1" aspectz="0.4"/>, and if you need 
to rotate, don't use 
another view point tag, you can use the rotx="somevalue" and add to the same 
line. I believe this can help.
