Thanks Musak, that was the problem. We had wmode=opaque because we were using an Iframe inside our app. Removing totally this parameter solved our problems. Now we'll have to return our reporting system to flashpaper.
Glad that it isn't a Flex problem. Alex, "What code-page are you using? Where is @ in that code page?" 1252 and yes, it's in that code page. "Does any other Alt-Gr combination work or is it just @." All combinations using Alt-gr. "Does AltGr+2 work for HTML pages in FF?" yes it does. João Fernandes
