Installing the 0426 version went well. All online updates installed ok.
Everything was good till I enter positioner setup-fine movement. After playing with the step e & step w, the sluggishness started to show up to the point that at the "exit" command the screen goes black for few seconds before you can see where you are in the menu. This is happening with Aura skin.
Fullnight hd skin performs a bit better with shorten lagging time in between the commands.
Overall, looks that it is an improvement for osmio4k+, fullnight hd skin, at least. Aura skin is still bad.
