wysiwyg editor not saving all changes magento 1.9.1.1

[DS209]

Hi,

looks like the wysiwyg editor in magento verson 1.9.1.1 has some problems with table and html savings!

I want to make a table to be centered in the Layout, but when i save the cms or block the savings are going lost

and the table will show on the left side on frontend.

The same settings was working well with the version 1.9.0.1

Someone else the same problems or a solution for this ?

Thank you very much for any help!
