According to the documentation, one can place the thumb on arbitrary
position along the scrollbar. This is supposed to take a float between
0.0 and 1.0.

However, the best I can do is get the thumb at beginning of the bar.
I've tried placing the thumb midway (0.5), for instance, in R3 and R4.

XtSetArg(arg[7], XtNtop, 0.5);            # in R3
XtSetArg(arg[7], XtNtopOfThumb, 0.5);     # in R4

The R4 docs provide a portable way to do this, but that does not work
either. If someone has run into this problem, and found a fix, I'd
appreciate hearing it.

thanx,
