Hello! I apologize if this is a dumb question. These past few days when I use the pen to draw in programs like Manga Studio and Photoshop, occasionally the pen seems to be catching or skipping, resulting in a short straight line in the middle of an otherwise fluid line. Here's an example: Can someone tell me how to fix this? It's a recent problem - it used to work fine. I don't know much about computers so maybe it's an easy fix... Thank you in advance!
