Quirky behaviour of some lists in IE7

I'm having a weird problem involving lists in IE7.

1. Go to http://sfl.london.on.ca/links_miscellaneous.shtml.
2. Look at the seventh and eighth links from the top, specifically Locus
Magazine and scifi dimensions.
3. Sometimes - but not consistently! - all of the background white (with
orange border) around Locus Magazine vanishes, as does the top half of the
background around scifi dimensions.

Moving the mouse around sometimes makes it happen and sometimes it fixes it.
Refreshing the page fixes it but the first time my mouse rolls over _any_
link on the page, the problem reappears. I can't find any errors in my CSS
or my HTML; there are some colour warnings in the CSS validator but I don't
think those are causing this problem.

This problem never seems to happen in IE6 or in Firefox 2.0.0.8 or Opera
9.54.

Any idea why this is happening and how I can fix it?

Rhino,

An important usability issue with your website is the inability to
easily and quickly distinguish text from clickable links. "Users
shouldn't have to guess or scrub the page to find out where they can
click." J. Nielsen.
Visual identification of links and figuring out what is clickable
(like a reactive image) should be obvious to visitors (including those
not familiar with your website, your choice of colors, etc).

3. Sometimes - but not consistently! - all of the background white (with
orange border) around Locus Magazine vanishes, as does the top half of the
background around scifi dimensions.

If the bug can not be reproduced reliably, consistently, it's going to
be difficult to recommend a workaround.
I was able to see the layout bug: it's a repaint bug. Still a bug
though. And a known IE7 bug too.

That's always good. I see no major flaw or obvious problem with your
code for now.

there are some colour warnings in the CSS validator but I don't
think those are causing this problem.

You still should listen to the warnings and follow the
recommendations: it is there for a reason.

Other things that I find more pressing, more important to do in your
webpages:
- figure out what is causing the horizontal scrollbar in the webpages:
this is always caused by an over-constrained design of elements, often
in the CSS code.
- Some links are missing a trailing (closing) slash:
