No problem using Opera 6b1 or MSIE 6.0 on this page.
K-meleon is v 0.6 build 547.
It seems that this only happens with script-generated options. It's a <a href=http://bugzilla.mozilla.org/show_bug.cgi?id=100181>mozilla bug</a> that was fixed, appearently, earlier this month. Probably means will be fixed when K-Meleon goes to Moz 0.96.
