tinymce(s) inside Tab(s) - first mce works, others not completely
jQuery UI 1.8.5
tinymce 3.3.9.1 (jQuery plugin version)
Dirt and simple: using tabs to store tinymce editors, like this:

First tinymce editors works fine.
Second and thirds and other tinymce editors don't:

a) See the suspicious Times New Roman font applied?
b) In Firebug I get a "J is undefined" for every tinymce from tab 2 on.
c) The changes I make to the text content, are not transmitted along POST data when I submit the form, always old unmodified data is transmitted.
Tried to initialize tabs first and tinymce(s) later and vice versa, with same result. If I comment out the tabs creation code, all tinymce instances works fine.
I posted the same question to tinymce forums with no luck by now, I hope someone had similar issues and solved, here.
The code to initialize tabs:
$("#tabs").tabs( );
The code (not all) to initialize tinymce(s):
$('textarea.tinymce').each( function(i,DOMelem) {
$(this).tinymce({
...
});
});
Thank you.
