hi, im on Windows 7 64 Home, and hv IE11 64bit installed. When i manually use IE to browse to the website, all seems ok, but when i try to use VS2019 VB.Net Webbrowser to browse to the website, im getting the 2 'errors' below everytime and the site will not work even after pressing 'ok'. I suspect Webbrowser is using 'compatibility' mode(IE8 or something from some web search).

1) An error has occured in the script on this page
Error: 'JSON' is undefined

2) Security warning
Do you only want to view the webpage content that was delivered securely?

I put this on Form load - MessageBox.Show(WebBrowser1.Version.ToString) and it show it is using 11.0.9600

I just add a new VB.Net Windows project, add Webbrowser1 and use a Button to execute it-
WebBrowser1.Navigate("https://www1.gtr368.com/")

Hv add this to registry but still the same:
[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/x-json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00

Thank you,
