Normally, playing Minecraft in fullscreen restricts the mouse pointer to inside the game itself. However, on 1.8.2-pre5, you can move the mouse outside the usual zone, allowing you to click things in another window. When you do, however, the game minimizes (for it's not actually designed for windowed fullscreen.)
If you move the mouse out-of-bounds and back in, you cannot move it out again. You would need to close and open the GUI again for the glitch to repeat itself.
Unfortunately, I cannot get pictures of this, because Print Screen doesn't capture the mouse. I am uploading a screenshot, but I had to draw in a mouse pointer where mine was.
STEPS TO REPRODUCE:
1) Launch Minecraft, switch to fullscreen mode (if not already in fullscreen)
2) Open a world (doesn't matter whether it's singleplayer or multiplayer)
3) Open any inventory, chat, or pause the game
4) Move the mouse pointer onto a secondary monitor. You will see that it can go out-of-bounds.

@@unknown: Are you talking about MC-68754?
@Redstonehelper I suppose that is part of the problem and related, but not what I'm talking about. My main issue is that, for some reason out of the blue, I could not move my mouse off the Minecraft window on to the next screen. The problem persists even after restarting my computer.
That is intended behaviour: The cursor should never leave Minecraft's fullscreen window. This bug report is about the Cursor actually being able to leave the fullscreen window, which should not be possible.
I see. Either way, the bug is still confirmed for 1.9.4 since my mouse was recently unbound until it got "fixed".
What possible convenience is there to having it locked at all times? The mouse doesn't become loose during normal gameplay and so doesn't cause any sort of inconvenience there. Instead, removing the ability to move across screens makes it noticeably more inconvenient for when you want to do so.
It may be a fluke, but I think I've found a solution. I had the same problem on Windows 10 however, I thought it was because I was running dual monitors. I tried switching to "PC Screen Only" but still had the issue... this is what worked for me:
find minecraft in the start panel
Right Click the app
open "app settings"
under app permissions:
turn "background apps" off:

Uploaded screenshot actually demonstrating the bug. Uploaded a third one to fix the gadgets positioning (I'm OCD and it was bothering me.)
