Dispose(bool)(if it isn't already, which VS.NET does automatically when you create a new class from the appropriate templates) and be sure to callAxWebBrowser.Dispose. This typically helps. The problem is basically a race condition. The window gets destroyed (hence, no window handle) before the control itself is cleaned-up.Microsoft MVP, Visual C# My Articles
