How do I make the mini-buffer window larger? It is not big enough to display up/down arrows by default

Question

How do I make the mini-buffer window larger? It is not big enough to display up/down arrows by default.

As can be seen below, the mini-buffer window is not sufficiently large to display the down-array and this bothers me.

Is there a way to increase its height so that its appearance adapt to its content?

It should be said, that I've installed the leuven theme and zoom-frm.el additions.

C-h v resize-mini-windows:

resize-mini-windows is a variable defined in `C source code'.
Its value is grow-only

Documentation:
How to resize mini-windows (the minibuffer and the echo area).
A value of nil means don't automatically resize mini-windows.
A value of t means resize them to fit the text displayed in them.
A value of `grow-only', the default, means let mini-windows grow only;
they return to their normal size when the minibuffer is closed, or the
echo area becomes empty.

To let minibuffer windows resize automatically, set this variable to either t or grow-only, in your init file. For example:

(setq resize-mini-windows  t)

But if C-h v tells you that the value is already t or grow-only then there must be some other problem. (In that case, recursively bisect your init file to find what is causing it.)
