A few questions

Hi! and thanx in advance for your time, if you can help me with these little quiz's:

1. Editor height works fine in IE (height=100%), however, in Mozilla, it's not set to 100%, but stays the same size no matter what I add to:

function FCKeditor( $instanceName )
{
...
$this->Width = '100%' ;
$this->Height = '100%' ;
...
}
Any ideas why this might occur?

2) Language definition only works in IE, not Mozilla, is this a common problem?

3) How to make the "save" icon/button to do something?

again, thanx for your time
