when I try to change my Avatar image and hit "Save", the pop-up box doesn't disappear, I get the "invalid action" icon over the save button, and the Avatar image doesn't update. I experienced this when uploading my own image from my computer and when selecting a set Avatar image. When I hit the "X" button in the upper right corner of the pop-up box the box closes and the new Avatar image appears in my profile. When the user hits "Save" the pop-up box should close and the Avatar should be updated. May I know how the popup is closing automatically?
