I am having the same problem. The cursor keeps jumping to the top of the note and is so incredible irritating.
I don't know if it is because of autosave, but I experienced it in the previous version as well as in version: 6.6.4.5512 (305512) Public, which I updated in today.
This bug / glitch is making Evernote so irritating and I have all my notes and work.
I can't even imagine having paid and had this problem.
Does anyone have any other suggestions, besides using the online platform?
Thanks
