Sorry My Engligh no good

so i couldn't explain well

here is screen shot what i have problem

First remove all content in content field
then just type This is test and press Enter Key 2 times and repeat it and view HTML Code then you can see "<div></div>"
and go to Preview Mode there is no Line space

I think it will be "<div>&nbsp;</div> or <div>&#160;</div>"

Go and try: http://cutesoft.net/asp/EnableAll.asp
