<hr> tag causes miss alignment of columns in IE

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create 1st row of columns w/ div.span-x, using .last for the end column
2. Enter an <hr> tag in one of the divs
3. Create 2nd row of columns w/ same widths as above row
4. Enter text in the same column as the <hr> tag above

What is the expected output?
A Horizontal Rule spanning the width of the column as set by .span-x, text 
aligned w/ the HR underneath.

What do you see instead?
Text underneath the HR is miss aligned when rendered in IE. But is correct 
rendered in Firefox.

What version of the product are you using? On what operating system?
0.7 on XP SP2

Please provide any additional information below.
If <hr> tag is removed, everything lines up correctly in IE.
