Using that source, I cannot replicate your problem. (I did
use my finger on the mouse rather than my tongue!) Zoom-
to-fit is active. Zooming works as Mr. Monsen describes.

Maybe it would help to describe what you are actually
expecting to see. The trouble may reside there.

Looking at your circuit, I find myself wondering if you
have dropped your 1 mS response time requirement.
What that unreal when you mentioned it awhile back?
