• Please provide any additional information below.

When the user goes to a certain website it opens a popup window. This window calls a javascript window.extern call back to the form which opens a new form. This is working with the default web browser object but the new form freezes for some reason with cefsharp. I've gone through the FAQ and troubleshooting guide but haven't been able to fix it. The code I'm using for cefsharp is almost identical to that in the quick start guide. The only extra thing I'm doing is calling "chromeBrowser.RegisterJsObject("external", this);" to register the form methods.

Avoid passing this in when you register an object, use a different method. Make sure you open your form on the UI thread, not directly in a bound method. Your probably blocking the render process.
