Cursor-following <div> - Disappears when mouse moves down or right

I'm trying to use this method to get a div to fadeIn when a user mouses over a text field that tells them what sort of information goes into the field. I've got the <div> to follow the cursor while in the text field if the user moves the mouse up or left, but when I move the mouse down or right the <div> disappears during the motion to reappear when the mouse stops. Here is a JSFiddle showing my relevant code and the odd behavior it's yeilding.

$(document).ready(function() {
    $(document).bind("mousemove", function(e) {
        $(".hover").css({
            "left" : e.pageX,
            "top" : e.pageY
        });
    });
    $(".num").hover(function() {
        $(".hover").stop().html("Enter a number").delay(500).fadeIn(150);
    }, function() {
        $(".hover").stop().hide();
    });
});
.hover {
	display: none;
	position: absolute;
	float: left;
	font-family: Calibri, sans-serif;
	font-size: 0.7em;
	background-color: rgb(255,255,230);
	border: 1px solid black;
	-webkit-box-shadow: 0 0 2px rgba(0,0,0,0.4);
	box-shadow: 0 0 2px rgba(0,0,0,0.4);
	padding: 1px 3px;
	z-index: 50;
}
input {
    margin: 30px;   
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class='hover'></div>
<input type="text" class="num" size="2">
I have tried applying the same .hover() JQuery method to other elements in my web page to see if it's a problem with applying it to a text field, but the down/right vanishing behavior persisted.

In my full code, the hovering <div> is created dynamically when the user first mouse-overs an element which produces the effect, but I couldn't get that aspect to work is JSFiddle.

Since this effect seems easily-produced by others I'd like to know not only how to achieve the correct behavior but also understand why my attempt came out so wonky.

Basically if your mouse moves over the .hover overlay, it generates a hover "out" on the item underneath your mouse. Moving the mouse left/right causes the cursor to move on and off the overlaid div.

Add pointer-events: none; to your .hover style. This will stop it being visible to the mouse and avoid generating any events on the .hover:

http://jsfiddle.net/4ba70vy3/6/

.hover {
    pointer-events: none;
    display: none;
    position: absolute;
    float: left;
    font-family: Calibri, sans-serif;
    font-size: 0.7em;
    background-color: rgb(255, 255, 230);
    border: 1px solid black;
    -webkit-box-shadow: 0 0 2px rgba(0, 0, 0, 0.4);
    box-shadow: 0 0 2px rgba(0, 0, 0, 0.4);
    padding: 1px 3px;
    z-index: 50;
}

Update: If the .hover was below the mouse, vertical movement would cause the same problem.

Also, as DevlshOne suggests, you might as well use the title= attribute on the controls and maybe just do yours for older browsers?

Just add a pointer-event:none to the .hover class
