#### Summary

I am trying to open a new window in windows desktop application through the **Developer Tools** but it seems to return a BroserWindowProxy object rather than opening a new window.

#### Steps to reproduce

open the Developer Tool for windows application and type the following in console:

> `window.open('','_blank','height:200,width:200')`

#### Expected behavior

Ideally it should open a new blank window as I have not provided any URL. It is not working even if I provide a url in window.open() method.

#### Observed behavior

It return a BrowserWindowProxy object.

Please let me know if I am missing something or it should be done any other way.

Thanks

Hi Mahipal,

Returning `BrowserWindowProxy` is intended behavior of Electron, which is the framework we are using to create the desktop app.

Just curious, why do you need a new blank window?

Hi yuya,

Thanks for replying.  
I am trying to render a custom Component inside the new window.  
Somehow, I am able to do that in Mattermost Web but unable to replicate the same in Desktop application.  
In case you want some more insight on what I am trying to achieve, you can check [this](https://stackoverflow.com/questions/49767544/window-open-is-not-working-in-desktop-application?noredirect=1#comment86550541_49767544) out.

Any help is appreciated.

Thanks.

Hi Mahipal,

Possibly `nativeWindowOpen` of `webPreferences` would help that. I have never used this option, so I’m not sure whether it’s appropriate.
