New Post: Debugging hangs if an event handler for a UI element is set and event handler gets executed (V8)

I've finally found the cause of the problem.

I host a chromium embedded browser (CefSharp) inside my application to integrate the debugger inside the application.

When a UI event which is bound to a script function is triggered and if there is a breakpoint in that function, the UI of the application freezes until the execution is resumed in the debugger.

Since the debugger interface is IN MY APPLICATON, I do not have the chance to resume the script because my UI is frozen and this gives me a frozen application.

When I run the debugger interface in an external Chrome instance, the Winforms application is frozen again when the breakpoint is hit but since I can click the resume button in the external interface I can unfreeze the app.

Can you imagine of a coding trick to overcome this problem?

As I wrote before I have the following "calling a delegate function in a new thread" option but this makes the code complicated and hard to maintain.
        public delegate void FormEvent(string eventName, object sender, EventArgs e);
        private FormEvent callbacks;

        public void RegisterToFormEvents(FormEvent eventHandler)
        {
            callbacks += eventHandler;
        }

        private void MainForm_Resize(object sender, EventArgs e)
        {
                new Thread(() =>
                {
                    if (callbacks != null)
                        callbacks("Resize", sender, e);
                }).Start();           
        }
