Successful deploy and run, but ">_ Terminal" feature is not working

Hi,

I’ve followed carefully this tutorial : https://docs.resin.io/raspberrypi/nodejs/getting-started/, and it has worked until the deployment and start of the app :
04.05.17 10:25:51 (+0200) Started application 'registry2.resin.io/testapp/ea51fe33f7cac8af562919a5e1caed75235229f6

I can access the “hello world” display here :

But now, when I click on “>_ Terminal” and then on “>_ Start Terminal”, the terminal blinks and disappear at once, am I missing something ?

Now I have to say after a full reboot of my computer, I can access the device Terminal. So maybe something was pending on my computer blocking the access, I had just upgraded Avast Antivirus without reboot…
