I ran into a big problem in firefox: the ALT GR key is disabled on some simple pages: (try entering an email)
This simple page DISABLES the ALT GR key.
<html>
<body>
<iframe src="http://www.dialogoo.com/vdialogoo.php?id=2" width="100%" height="100%"></iframe>
</body>
but if you open
http://www.dialogoo.com/vdialogoo.php?id=2
ALT GR works!
This strange behavior only happens in Firefox! It seems Firefox + Iframe + Flash = disable ALT GR key!
