Not sure. Are you setting the background colour to LIGHTGRAY or BG_LIGHTGRAY?
Is the ANSI content being loaded before or after the scrollbar is opened /
cycled for the first time?

The ScrollBar doesn't actually redraw itself when you call .cycle() on it; it
just updates its position info. The drawing takes place when .cycle() is
called on the parent Frame. You could try calling .cycle() on the ScrollBar
after you have called Frame.scrollTo() but prior to calling Frame.cycle().
(That may or may not help, but it's worth a shot.)

Probably just differences in the way you're using it and the way I expected to
use it. In my input loops, I usually use console.inkey rather than
console.getkey, and call [whatever].cycle() each time through the loop. This
way, stuff gets updated as needed whether the user has pressed a key or not.
(Useful if you want to update stuff in the terminal while the user is idling,
etc.)
