However, it does work when I hold down ctrl or shift and highlights text or moves the cursor the way you'd expect it to in these situations. Here's the weirdest part, it works on the password field of the log-in screen, but not once I've logged in. And then sometimes it works normally.
Anyone have an idea what could cause this and how I can stop it? I'm guessing I have some hotkey set up that I don't know about, but I don't remember installing anything that would do this.
