Update 2 – 10.01.2012:
I was asked about the “Use Google Libraries” plugin for WordPress – here it is: http://wordpress.org/extend/plugins/use-google-libraries/
And this explains why you may wanna use it, even if your visual editor works fine: http://encosia.com/3-reasons-why-you-should-let-google-host-jquery-for-you/
Thx Dave !

Wow – I found a new method to fix it. But honestly I don´t believe in it and wouldn´t recommend it further. But for me it worked (NO joke).
I wrote this text below with the Wordpres iPhone App because I couldn´t use the web cause the visual editor was broken. And after this article was successfully posted from the iPhone, I tried the visual editor again. And now it worked. Crazy ?! I think so…
Grrrrrrrrr…after updating to 3.3.1 the visual editor is broken. Again. The same shit happened after updating to 3.3. Last time I fixed it by installing the “Use Google Libraries” plugin. This worked fine for 3.3. But it doesn’t seem to work for 3.3.1. And the WordPress support groups are not a real help. Definitely not…damn !!!
