Hi dELTA, think I've found a small bug. If I go to the library then click on "My Contributions", on the resulting page I am unable to expand the "by target"/"by tool" categories. When I mouseover the + symbol an underscore appears; clicking the + does nothing. It's as though the CSS for that icon is broken on that one page. Clicking the library logo (or manually returning to the front page) lets me expand the categories as normal.

Firefox 2.0.0.11.
