are you serious that someone actually thinks locking my display in full screen is a feature?
It's a wonderful feature. I use it all the time. However, I use it without Auto-Hide. E.g. while in Fullscreen mode in IE Desktop you can press Alt-Space,H to toggle the Fullscreen window's Auto-Hide option off.
Then instead of being blocked in by having a window in its Maximized state or even worse by having its normal mode window maximally sized, I can just press F11 to toggle it into a smaller normal mode window and do whatever I need to do with other windows while seeing some of that one.
now I have to have that PDF doc full screen, which means I simply cannot do what I want?
Which app has made that happen? If you mean you are seeing the Modern UI Fullscreen (MUF) Reader app that could mean you should be installing a different program to read .pdf files, such as Adobe's Acrobat Reader or Foxit and let it be the default program for .pdf files.
BTW I have never seen this small message window that is being referred to. Like others I would wonder if it is a feature of a particular site or app. E.g. if it is something that is being sensed by a website being viewed in MUF IE, thinking only of how IE Desktop users would see it, then you could use the right-click Tools button to open the same page in an IE Desktop window, where you could use F11 if necessary.

Full Screen is not a feature one needs on a 30 inch LCD... it really really sucks when your trying to work... it allows NO control of our MULTITASKING environment if we can't re-size what WE need... So they really really need to fix this PROBLEM... I'm running a i7 hex core processor with 16GB of Ram not some stupid tablet.
