Form closing when gecko browser shows popup

Question

I'm using GeckoFx-Windows-22.0-0.7 and when I click something a popup with yes and no options is shown. My form closes without triggering FormClosing or FormClosed event. How can I solve this ?

It closes always before 3. popup.

I solved, Adding this code GeckoWebBrowser.UseCustomPrompt(); before Gecko.Xpcom.Initialize is solved my problem.

Thanks
