Dear Adam,
Thank you, my problem with the html not displayed as it should is solved now.
I have noticed that the problem with the HTML view that displays the HTML as in WYSIWYG when I paste my HTML is only appearing when I copy/paste html code from Visual Studio .NET, when I copy/paste from Notepad or Dreamweaver the problem does not appear. It's quite strange.
But anyway my customers are not using VS .NET at all so they won't see that problem.
Thank you for your help.
Kind regards,
Sébastien.
