I've been trying to find what is causing the double posts since the last two days. The only think I can see is about the INPUT TYPE=Image that I changed in order to benefit of the spacebar capability for the submit on that image. For some kind of reason, this seems to conflict sometimes and causes double posts. So, for the reply ability either from the original message or from the preview window, I have removed the INPUT TYPE=Image and replaced that with a standard image HTML code. However, that disables the spacebar capability to submit the form. So, for a while, for some tests, that will be the case. So, don't send me emails or reply here to ask why the spacebar doesn't work to submit the form. :)
