Social button causes icon to appear

[BJNees]

I click on the social button as soon as I do, I get what looks like a file icon in the lower left area of my screen, mousing over it causes it to glow yellow but has no functionality with either a left or right click, I cannot remove it under carb options, and anytime I have created a new toon, as soon as I click the Social button it appears. Any suggestions? Thx
