Ok so my problem is just as the topic title says, when I press f11 and go into fullscreen a black bar takes over the bottom inch or so of the screen but for some reason I can still see the items in my hotbar so I know that it is nothing to do with my aspect ratio and it is definitely a minecraft problem not my computer because no other games do this. If anyone has had this before then can they please help me out, this is very annoying. :/
I seem to recall in XP there was a setting for the taskbar called "always on top" is it set to that bychance?
Not every game uses the same method to draw to the screen.
Yes there is a setting called "always on top" and it is on, but I would rather keep it that way, however I was thinking about what you said about having the taskbar on autohide, so I thought i'd try it.
It worked and the black bar is gone, I will just leave the taskbar on autohide and when I want to see the taskbar I'll just put my mouse at the bottom of the screen.
