I open a window with the following sequence:

	prefposition(10,990,10,990);
	mainwin = winopen("Name");
	keepaspect(980.0,980.0);
	minsize(98.0,98.0);
	winconstraints();
	doublebuffer();
	RGBmode();
	gconfig();
	mmode(MVIEWING);
	
	/* set up hidden surface elimination */
	zbuffer(TRUE);
	czclear(0,getgdesc(GD_ZMAX));

	/* Intialize the eye position and orientation. */
	perspective(500,1.0,1.0,400.0);
	polarview(2.5*WorldMax,0,0,0);
                      ^^^^^^^^
			  ^
The value of WorldMax >>>>^  is based on values in the input data file.

Problem:
When I read in a new data file, recalculate WorldMax and call polarview
with the new val of WorldMax, the view is not modified.  Very strange.
I noticed that on the polarview man page it says:

     The matrix computed by polarview premultiplies the current matrix, as
     specified by mmode ....

Could this be part of the problem?
