Hello, can u help me with this issue ![image](https://europe1.discourse-cdn.com/katalon/original/3X/e/e/ee1181a6fe825976d43367c5907a2757fcf804cc.png) the message box appears and disappears as long as the test is running. after the test error, I click the approve button(with chrome is being controlled by katalon) and a pop up appears and doesn’t disappear. but when the test is run a pop-up appears and immediately disappears so it can’t click on the message box (ok) ---

@bcamfchristian, try the following: ```auto WebUI.waitForAlert(30) WebUI.acceptAlert() ``` ---

If you do anything else (involving WebDriver, I believe) then WebDriver will handle the alert itself and issue an error. ---

I can save you the pain I went thru, you’re welcome to read thru the back and forth, but there are two possible solutions at the bottom you may like to try [Alerts are displayed, but disappear before I can accept it - Katalon Studio / Tracked Bug Reports - Katalon Community](http://forum.katalon.com/t/alerts-are-displayed-but-disappear-before-i-can-accept-it/60318/3) ---

This workaround worked for me. Navigate to Project \> Settings \> Desired Capabilities \> Web UI \> Chrome: unhandledPromptBehaviour=ignore unexpectedAlertBehaviour=ignore
