today, I ended up uninstalling Kaspersky Internet Security with Kaspersky Labs remover tool and reinstalled it. Problem! I lost my bloody weather gadget. I tried dragging it out again, all that's there is a little info icon, that little 'i' and I can close the gadget by hovering around it. There's literally nothing there.
I tried killing the process and starting it back up again, nope. I tried using the 32 bit gadget process, nope. So I'm thinking there's something that uninstalling Kaspersky did.
