Bullets don't show up in unordered lists in Internet Explorer

One problem with the theme Contented7: Bullets don't show up in unordered lists in Internet Explorer, same for ordered lists. In Firefox, everything is OK.
You can see it yourself on http://tcp-lp-mod.sourceforge.net/ in the article "TCP Low Priority module (TCP-LP-MOD)".

ax came up with the solution:

Remove the list elements (ul, ol, dl) from line 26 of style.css.

Explanation: margin:0.75em 0; means also margin-left is 0, which makes the bullets, which in IE apparently are "in the left margin" somehow, disappear.
