Just a quick post that may help out a bit. I was recently working in Adobe Premiere and some how through a few erratic keystrokes made my minimise, maximise and close button icons in the top right hand corner of my screen DISAPPEAR!. After some painful searching I found a couple of solutions, one involve going to the documents/ adobe / Premeiere pro / “latestest setting folder like 11.0 etc” and deleting it …… you loose some saved work top settings but it does do the job.

The BEST solution is to press Ctrl + CMD + \ this will toggle the icons on and off ……….. hope this helps.
