If you look at my art blog
http://www.tomsemmes.com/blog/ and look at today's posting (MArch 24) you will see that the image that I inserted in the middle of the text overlaps the post below it.
I have tried several times to add space at the end of the post so it doesn't do that, first my merely hitting the return key then by going into HTML and pasting
<p> </p> several times. Each time I save the post, these spaces are automatically deleted. Any idea why?
