Chrome is launched when clicking Cancel on login screen

[anguscrombie]

I'm using the WinFormsSample project and I'm running into an issue whereby Chrome is being launched and browses to the redirect url when clicking Cancel on the login screen. I'm using the IdentityServer4 sample (https://demo.identityserver.io) but the same thing happens with another auth provider i'm using.

It seems that NavigateError can't tell whether the user has cancelled. I guess in a web application it makes sense to send the user back but in my case i'd like it to just close the form and definitely not launch chrome. Is there a reliable way i can achieve this? Also, apologies if i have raised this in the wrong place, i'm new here :)

Is anyone able to shed any light on this?
