I have a problem on several browsers except for FF.
I have a p element with the default text and I transform this element into a tinyMCE editor.
The problem is that the content isn’t displayed at the top of the editor and I didn’t found a solution.
Here is a screenshot of the problem :

The right part is the default content which is not at the top.
The left part is when I remove the content on focus and start typing something. It gets back at the top.
I still have this issue but it not due to tinyMCE.
I removed some style myself in javascript.
