This example comes from maple converting Thiele2Confrac.
It may come from other maple instance(s),
as well as sometimes from native Smath [can be doctored generally]
In this example, some coefficients can be evaluated, this one NO !
In short: a BigNumber can't be assigned.
It may require the 64 extended floating point ?
That's your Saturday delight ... Jean

This reminds me of a problem which I observed more than once:

Can you actually scroll to the right and see the end of the expression?
In my SMath instance (7005) I can scroll a bit but then the region with the big number disappears even though the slider of the horizontal scroll bar isnt even in the center of it's way to the right.

Yes Martin, can slide to the end 5½ pages wide.

This issue is fixed already in latest available build. Plan to release next Stable today or tomorrow.
