-Adding "overflow: visible;" (or removing "overflow: auto" from style.css) makes the sidebar appear above the recentchanges rather than below it (like the third screen shot above). Unfortunately because ".recentchanges .pagelinks" uses "float: right;" it doesn't look look exactly like the third screen-shot. For this reason I use the "clear:both;" as well.
+Adding "overflow: visible;" (or removing "overflow: auto" from style.css) makes the sidebar appear above (as in printed over the top of, not higher up the page) the recentchanges (similar to the third screen shot above). Unfortunately because ".recentchanges .pagelinks" uses "float: right;" it looks strange in other ways. For this reason I use the "clear:both;" as well.
