Hmm. Special:AllPages works for me on my wiki.

aude if it matters at all, i'm in chrome now
aharoni aude, Nikerabbit - true - it breaks in chrome
aude ok, browser specific
aude think i found the line of code that might be a problem
aude if i comment out $( 'html' ).click( $.proxy( this.hide, this ) ); in jquery.ime.js
aude then it seems to work
aude don't know what that is supposed to do
aude well, other than what the code comment says

issue also applies to the search box, so can occur on any page

That's because #hide returns false, preventing all other click handlers, including browser's native ones, from running…

I'd submit a patch, but it's a really annoying process for ULS.

Someone should probably just remove that "return false;", in this function and maybe a bunch of others, since they don't seem to need it either.

Or alternatively, replace that line with $( 'html' ).click( function () { imeselector.hide() } ); to gobble up the return value and be more careful in the future.

I submitted one after all. https://github.com/wikimedia/jquery.ime/pull/261
