So, several times now, across multiple computers, I've had Opera just randomly decide to pin itself to the taskbar (just happened again today). This is quite infuriating, because I never pin anything to the taskbar. Is this a bug, or are you intentionally telling it to do this? If the latter, I really wish you'd stop, and if it's the former then I hope you can fix it. I don't like having to wrestle with a program to make it do what I want.
I realize this is only a minor annoyance, but it's still an annoyance.
