Whenever I press shift, it acts as if I pressed both shift and escape, meaning when I'm in Google Chrome, it opens up the mini task manager, or when I watch a video in fullscreen and I press shift it exits out of fullscreen. I went into another program to see if it was just chrome, but it did it again. I also noticed that pressing ctrl activates the windows key, which is annoying as well. This is a one day old keyboard, so I don't understand how it could have a problem this big.
EDIT: Seems to have fixed itself. That was weird...
