cursor jumps back during typing

[takaa]

All kinds of posts here, except the original poster.
Guess the battery was replaced, and that was the end of that.

The problem is not due to the keyboard, I am typing on a new MacBook pro. Also the trackpad can be ruled out as I am typing extra careful. 

I have done some checking and I think the problem is due to a program called "Grammarly" This program is a grammar/spelling checker that is working in all screens. Everytime he wants to make a correction he jumps my cursor back to the place where a change is suggested (which also explains why at the end of a post it is getting increasingly more difficult to type since he is constantly jumping back to previous places). This does not happen everytime, but i am fairly certain this is wat causes my problems. This website is the only place I have experienced a problem with this program running in the background. At least we now know what it is. Tnx for the input
