从Adobe AIR应用程序打开电子邮件弹出窗口

I need to open several email popups (~30) from Adobe AIR Flex app, I am currently using navigateToURL but I observed that at times some email popups go missing. I have tried callLater as well. WHen I introduce delay between popups it works better but still has a risk of some popup missing. Can anyone advise please? These emails dont have any attachments but have html contents.I need to open several email popups (~30) from
