Need steps to reproduce it or a live example at fiddle.tinymce.com

Settings for TinyMCE.init():

oninit: myCustomInit

myCustomInit function declaration:

function myCustomInit() {
    if ($.browser.mozilla && $.browser.version.indexOf("11") == 0) {
        setTimeout(function() {$('.mceIframeContainer iframe').each(function(i) { $(this).height($(this).height()+1); });},3000);
    }
}

Note: I have reverted by changes from my ealier post to tiny_mce_src.js, so the piece of code above should be enough to get it working.

I have been running the 3.2.7 install for years now with no problem.. now I have to go back to all my clients websites and update... ??

Really ?

It works for me...

oninit: function() { 
    $('.mceEditor .mceIframeContainer iframe').each(function(i) {
        $(this).height($(this).height()+1);
    });
}

On a page with 3 WYSIWYGs, only the last one is editable. For the first two, I still need to resize them by dragging the bottom right corner before their content appears and the box becomes editable.

It forces the already loaded tinymce iframes to resize, and this problem is gone.

<script language="JavaScript">
  $(window).load(function() {
        forceTinyMceIframeResize();
    });
    function forceTinyMceIframeResize() {
        $('.mceEditor .mceIframeContainer iframe').each(function(i)
        {
            $(this).height($(this).height()+1);
        });
    }</script>
