I try to add an avatar. I go to my Personal Details. I go click on the avatar: I then see I then select an image from my hard drive (dimensions 600x576, 490kB) For a second after I add it, I see a loading animation in the top right corner. But after that, nothing changes. If I press Okay, nothing happens. If I press Close, nothing is saved. Is there a (very small) file size or dimension limit that it's not telling me about? All it's telling me is the image has to be at least 200x200 pixels (which mine exceeds handily).
