Great! Thank you so much! I've been trying to simulate the problem consistently and I'm pretty sure I've succeeded. The problem is happening pretty consistently when I place the knuckle of my pinky down a fraction of a second before the pen. I think when my knuckle touches its starting the one second countdown so when I finally place my pen it chooses the color picker almost instantly. I'm using light pen pressure and drawing a small dot -- which I was using to make guidelines using the "continue last" feature. I'm working on making a video of it but its coming out kind of dark. I'll try another method later. Please try and see if you can simulate the problem by placing the knuckle of your pinky finger first and drawing small dots. Thank you for your efforts!
