All of my widgets look great in Firefox, but in IE8 they are showing circle bullets as well as the colored blocks.

I'm using the Post Query plugin, but I don't think that's messed anything up because when I deactivate it the built-in Links widget still shows this style issue.
I know there's a rogue piece of code somewhere that I'm not seeing.
Help very much appreciated, as always,
Julie
