Googling it hasn't turned up anything yet so I'm trying here:
I have windows 8 and use Chrome, since yesterday everytime I open chrome the windows is full size and I can't see the desktop bar (with everything that is open, the time..). It's not in F11 mode since I can put it in F11 (that makes the chrome's open tabs disappear).
I don't know how I did it, I just want to be able to see everything

The minimise/close buttons on the top right hand have also disappeared, I'm lost, any one can help me?
/ while using the 'spell check' turns out it opens in a new tab, not a pop-up window like it should..
OK, never mind, found it. It was in windows 8 mode, you just have to click on 'relance chrome in desktop mode' or something.
I'll leave the Q&A in case it can be usefull for anyone.
