Set mouseout area?

Hello, I am new to Animate and have a problem with a banner of an HTML5 canvas file.

In my banner is a button of 1 x 2 cm. On this button is the following action: on moueseover the animation jumps to a certain frame and continues playing the animation from there. On mouseout the animation jumps back to another frame and continues playing the animation there. This works almost wonderfully, even mobile. But the problem is still this: If I have triggered the mouseover and only shake or move the mouse very slightly, mouseout is triggered directly. But it should only be triggered when the mouse leaves the button of 1 x 2 cm.
The Script is on the button:

var _this = this;
var frameNumber;
/*
Durch Bewegen der Maus über die angegebene Symbolinstanz wird eine Funktion ausgeführt.
'3' gibt an, wie oft das Ereignis ausgelöst werden soll.
*/
/*stage.enableMouseOver(3);
_this.info_1.on('mouseover', function(){
/*
Verschiebt den Abspielkopf in der Zeitleiste zur angegebenen Bildnummer und setzt die Wiedergabe ab diesem Bild fort.
Kann in der Hauptzeitleiste oder in Movieclip-Zeitleisten verwendet werden.

_this.gotoAndPlay(411);
});*/

/* Mouse Over Event
Mousing over the symbol instance executes a function in which you can add your own custom code.

Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the symbol instance is moused over.
frequency is the number of the times event should be triggered.
*/
var frequency = 1;
stage.enableMouseOver(frequency);
this.info_1.addEventListener("mouseover", fl_MouseOverHandler);

function fl_MouseOverHandler()
{
	frameNumber = this.currentFrame;
	// Start your custom code
	// This example code displays the words "Moused over" in the Output panel.
	_this.gotoAndPlay(467);
	// End your custom code
}


/* Mouse Out Event
Mousing out of the symbol instance executes a function in which you can add your own custom code.

Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the symbol instance is moused out of.
*/
//var frequency = 2;
stage.enableMouseOver(2);
this.info_1.addEventListener("mouseout", fl_MouseOutHandler);

function fl_MouseOutHandler()
{
	if (frameNumber > 330)
	{
		_this.gotoAndPlay(330);
	}
	else{
		_this.gotoAndPlay(330);
	}
	// Start your custom code
	// This example code displays the words "Moused out" in the Output panel.
	//_this.gotoAndPlay(frameNumber);
	// End your custom code
