Hi, I am having the same scrolling problem - it started very recently - no, I have not installed anything since the problem has arisen
I use evernote in my browser (Mozilla) and use Win 8.1,
I have never had this problem & I have been using evernote for some 4 yrears now
I have closed and reopened evernote, & restarted the PC,
It does not happen in anyother tabs
Has anybody found anything actionable that could be utilised other then telling me that you have never experienced this before😀
