Opera window follwing dragged tab to another monitor
Unfortunately for me, everytime I want to drag and drop an opera tab to one of my other monitors, Opera itself, follows up and starts maximized, but behind the dragged tab. This is actually really, really annoying. Video of my issue: https://www.youtube.com/watch?feature=player_detailpage&v=sACjFbxTnhA
Some applications aren't multi-monitor aware. Chrome has had this problem in the past and I'm assuming that Opera does as well.
Windows multi-monitor support is pretty rudimentary. I use Dexpot to manage both multiple desktops and multiple monitors, it's smart enough to manage apps that themselves might not be multi-monitor/desktop aware.
