# Why Does the Screen Freeze After Closing the OSM Campaign?

> Webpage freezing after closing an On-site Messaging campaign? Add the required trackDismiss and dismissMessage functions to the close button.

## Problem

The webpage experiences a temporary freeze after the On-site Messaging (OSM) campaign is closed.

## Solution

To resolve the issue, ensure the following functions are included under **Settings** > **Styling** > **Custom Attributes** in the close button when closing the OSM campaign:

* MoeOsm.trackDismiss();
* MoeOsm.dismissMessage();
