Can't drag text
Does anyone know why I can't drag text in High Sierra 10.13? Text based applications like TextEdit, MarkDown and database editors don't allow me to drag the selection. I can select text normally but when i try to drag the cursor just slides off the selection. If I restart the application dragging works normally for a random period like several hours. But I can't constantly restart applications.own a
