Odd Unidentified Window Popping Up Randomly

[gibsonjsh]

So I've noticed a strange window popping up at the bottom of my screen every once in a while when working on my Retina MacBook Pro.

Anyone have any ideas as to what it could be? Should I be worried about malware or anything like that? Thanks in advance everyone!

I may have figured it out...

So after some trial and error and some aimless clicking around, I think I discovered the culprit: Adobe's Creative Cloud's menu bar item. When I click up there, the window pops up at the bottom of the screen. When I click off the menu bar item (close it,) the long skinny window disappears after a few moments. I've never seen this before, so it looks like I'll have to get in touch with Adobe and see what the deal is. I'm sure it's harmless however.
