**Short description of error**
This bug appeared one day (until this day, everything works fine) and I can’t solve it. Even trying to delete all Blender folders and installing again. I’ve tried to install another versions and the portable versions and the issue is repeating. The same problem appears always.
The thing is that the Info Menu doesn’t appear (it's under the caption bar of the window). In the default view, I tried to change another window and put the Info Menu, for example in the Outliner Window, but suddenly, the bar disappears always.
Moreover, the arrow of the mouse it’s displaced like a 1 centimeter. I mean, when I try to click in a button, I have to point a little bit below of the button. I attached an image to explain better this point.
