It was difficult to reproduce, so most likely Alex simply gave up.

As I posted here I couldn't reproduce it.

Yes I know; although I was hit by the effect, it was very difficult to reproduce it anyway. It was only seen in IE6 (on my XPProSP2); just tried it again a couple of times, but right now I only have the latest version of IE (6.0.2900.5512 XPProSP3) and could not reproduce it either (IE7 always worked anyhow). Sorry, but I have no ideas how to deal with it (the CSS seems to be OK for me...).
