Skybound Gecko Project: Attempted to read or write protected memory

I am starting out a pretty simple project - essentially a web browser with a hard-coded URL for public terminal use. That is to say, it WOULD HAVE been simple if the C# web browser control didn't make me want to commit suicide.

I decided to go with the Skybound Gecko browser, as it seems to be the only feasible alternative.. I went through some of the learning curve with this project, and got around several "Starter" errors (ie. cannot navigate before setting window handle, and the error when xpcom.dll can't be found), and have corrected them

Now, when I go to run the application and open the URL in a Skybound Gecko Control, I get an error in Program.cs.

Also, on a side note, I installed Stylizer 5 and it utilizes the Skybound project properly, so I assume it's in my code or config.

Any assistance would be greatly appreciated.

Program.cs (where the error is shown)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace alphaCommKiosk
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            //Error Line--------------------------------------------
            Application.Run(new Form1()); //  <--- ERROR OCCURS HERE.
        }
    }
}

    Skybound.Gecko.Xpcom.Initialize(path);

    webBrowser1.CreateControl();
    string u = "http://www.domaion.com/kiosk/index.php?account=" + mAccount + "&hash=" + mHash;

I was able to resolve this day-long issue by switching over to the WebKit component. Frankly, if I had found this first, I would have preferred a "chrome-esque" control over FireFox, anyway.

Super easy to install and none of that problematic xulrunner garbage
