It was the Skin Manager Plugin. Changing back to default fixed it.
I will post this answere to every thread, since I want to let everyone know that I appreciate the support and Help that I got from ya’ll.
Thank you a lot!
Also for you in particular: if you used introskipper: its best to wait some time i think. At least my introskipper is not compatible anymore on my 10.9.x instance. On 10.8.x instance it is running. Gotta wait for a update for this plugin i guess.
Yeaaahhhh. This is definitely still falling under the NSFW Category. :D
Not porn per se. But definitely not something to have playing at work. ^^
