This is a stripped down version of the gallery page in Eric Meyer’s
css/edge sub-site. It demonstrates a strange bug in MSN for OS X. The
set of circumstances are as follows:
an absolutely positioned div (the gray area )
with
padding
specified
but no specified width, either by specifying width
, or specifying both
left
and
right
.
There also needs to be an image in the div somewhere - presumably some
other kinds of replaced content will do.

The problem is that the text of the paragraphs all goes onto one line (unless you explicitly use line breaks as in the description of the bug shown above the image) . So the absolutely positioned div gets wider and wider and wider and wider and wider and wider and wider and wider....
sometimes you might need to switch to another application and back.
