You know the two little buttons on the side of the pen? One is the eraser function on OneNote, the other is the function used to select pieces of your notes. Well the selection button works, but I have to press and hold the button super steadily or else it will not work. So like, midway through selecting a chunk of my note, carefully selecting the parts of the note that i want to actually select, the tracing line would suddenly disappear and I have to start tracing all over again. its like the button loses connection for like a split second and then I lose any tracing i did. It is so effing annoying. Hey, you know that diagram you just spent 3 minutes trying to trace and select? Great, now trace it again.
