Hi Adventurer5... As there are a variety of Chromebooks on the market, most of which have slightly different operational methods, It might be helpful to those who can assist you, if you make it clear which model you are referring to...
I have an Acer C720 which I've found to be a very reliable little machine...
Where the touch-pad is concerned on mine (and that of a friend) we've both found the tap (to activate) sequence of the pad to be 'over sensitive' so we've both switched that facility off ~ which can be accomplished in the settings section...
Having done so, I find that the actual 'press to activate' area of the touch-pad (lower section only) works very efficiently, especially if combined with the use of the 'Alt' key: which produces normal (as would be with a mouse) right button functionality...
You may well be aware of this, but I thought it might be of interest if you'd not...
But as for experiencing a sticking sensation (I take it the pad sticks in the down position on the right) I've never experienced that at all... Sorry I can't be any more helpful than that...
Robbie....
