I have a K400 - the Options+ program has messed up my two-finger scrolling which is critical to my use of this keyboard. The original logitech software did not have this issue and i was able to correct it. Please do something because the scroll momentum/acceleration or whatever is happening is a known issue with Options+ and i can't go back to just the original Options because I have other Logi devices (4) and need the receiver control. I have 6 logitech devices if you could my headphones and would really love to see this fixed. thank you!

this issue is being reported elsewhere to the point it is 'known':
