WPF WebBrowser control, jQuery, Windows 10 - Long running script error

0
votes

I have a wpf application that is using the WebBrowser control to render a website that I have. The website relies on jQuery 2.1.4. The website is using the default html doctype and has the <meta http-equiv="X-UA-Compatible" content="IE=edge" /> tag. I have also added a registry key for the wpf application which sets FEATURE_BROWSER_EMULATION to 9999. All this was working just fine in Windows 7 and 8 running IE 9-11. I've now upgraded to Windows 10 and once in a while I'll get an error that states:

Stop running this script?

A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive.

After stopping the script, I get a bunch of script errors that basically state that jQuery or '$' is undefined. I assume the long running script was jQuery. If I close the WebBrowser control window and reopen it everything works fine again, but then later if I open up the WebBrowser control I'll get the same error messages.

Is this an issue with me having the FEATURE_BROWSER_EMULATION key set to 9999? Will setting it to, say, 11000 or 11001 fix this issue? It's difficult to test since I don't always get this error. Most of the time if I open up the WebBrowser control it will work just fine. Does anyone know anything about this issue or have the same problem?

Thanks in advance!

The FEATURE_BROWSER_EMULATION key seems to break the Webbrowser control in Windows 10. For me, I had to remove the key from the registry. This wasn't really a problem for me, since i have control of the code, and by using the in the HTML i got the same result as with the key in Win 7/8/10.
