How to? TCMD Configuration Dialog: 'Smooth Scrolling' Option missing?

Dec 17, 2009
Is there an option missing in this dialog box?

The documentation mentions:
Smooth Scrolling scrolls the Take Command tab windows smoothly (2 pixels at a time instead of a line at a time).
This will slow down scrolling and output from fast programs. The smooth scrolling is only visible if the underlying console
window is scrolling two lines or less, so if the tab window is displaying a lot of fast output you probably won't see it

We also have this entry in TCMD.INI: SmoothScroll=No

But there seems to be no corresponding radio button etc. in the dialog?
