In the Monobook skin, under IE and Opera, the borders of the tabs (edit, move etc. - with the exception of the currently active tab) on top of the article don't quite attach to the block below - there is a small gap (one pixel with usual em sizes). Hard to notice, but it is rather ugly once you do.
Under Opera, #p-cactions { margin-top: 1px; } seems to fix it, and under IE 6, #p-cactions a { padding-bottom: 1px; } works.
(Tested under IE6, Opera 9.63, Opera 10 beta on Win XP. The problem also appears on IE7, but the fix was not tested there.)
