Changing the standard modal dialog form

Hello all,

I'm able to make changes to the layout via CSS commands e.g.

div.DTE_body_content {

height: 600px;
width:1000px;
overflow:scroll;
}

I want the following:
* How to allow the end-use to resize the window. div.DTE {resize:both} doesn't work
* How to allow the end-user to move the window on the screen
* Most important: when you click outside the edit window the form is immediately closed (it looks like a cancel). Normally with modal diaolg forms you cannot click outside the window. Probably it isn't a true modal dialog form.

Kind regards,
Frans Kraak
