There's probably a way for me to not collapse on a double-click-and-drag. But you should consider switching over to single-click-and-drag! Saves loads of clicks over the course of a year!

Double-click and drag makes the selection be whole words, which saves time over having to find the start and end more precisely. (I actually often triple-click and drag, for selecting whole paragraphs)

Whoa! As someone who compulsively clicks on text to select it while reading, I can't believe I've never realized this.
