Despite being a real "Vuescn Veteran,"
You have my sympathy...;o)
Even on a 3GHz processor movement of the sliders on the
new tiny diagrams is jerky and I did what I did so often
previously already: I reverted to an older well proven
version 8.1.30.
I seem to recall one setting to modify the way screen updates are
handled.
As far as I remember, VueScan default is to refresh the whole screen
after *each* keystroke!? Unfortunately this takes too long and it
causes VueScan to "eat" keystrokes i.e. they are ignored until the
screen is fully redrawn. The recommended "solution" is to turn this
screen refresh off. However, this also means the display will no
longer correspond to the settings and has to be updated manually. :-/
Maybe, you have this setting on, and that's why the movement of
sliders is jerky as the whole screen is redrawn every few pixels?
This new user interface is an enigma to me.
VueScan has a user interface!? Since when? ;o)
