ok, so it's in the form that the problem happens not the email itself...
in the webassist/forms/fd_newfromblank_default.css file edit the following css:
form.NewFromBlank_Default textarea.formTextarea_Medium {
background-color:#FFF;
padding:5px 5px 5px 5px;
width:382px;
height:150px;
white-space:pre;
overflow:auto;
margin:0;
margin-left:2px;
}
to:
form.NewFromBlank_Default textarea.formTextarea_Medium {
background-color:#FFF;
padding:5px 5px 5px 5px;
width:382px;
height:150px;
white-space:pre-wrap;
overflow:auto;
margin:0;
margin-left:2px;
}
