stagewebview problem with https and an invalid certificate

Hi,

I'm using StageWebView to display an html page with https and an invalid certificate, and I'm finding a very strange error. It works ok when I install the app on my iPad, but if I force to close the app, and then I open it again, the html page is unable to load even if I close and open the app (not forcing this time)

Can anyone help me please?

Thanks
