#5 text output scrolls

[Anonymous]

With some font types different from lucida consol
(for instance times new roman) the usage of the
Adjust Levels' slider also makes the text
image 'slide' (rather scroll) up/down (it works
mostly when the image doesn't fit a single screen &
is scrolled to the bottom).

switching Invert the Font also 'lifts' the screen to a
different part of the text-image compared to where it was
before turning it on/off.

all other sliders affect the scrolling in the text window
(ie. brightness, contrast)

This is caused by the RichTextBox control with variable
width fonts (or possibly when the conversion takes more then
a certain time to complete), and I currently haven't found a
way around it.
