Conflict with result set if there are 2 or more jquery autocomplete on same page

1. If you type some letters into a contact reference widget in a form, and then type letters into the Quick Search widget w/o reloading the form - the Quick Search widget no longer responds (i.e. type in letters, nothing happens). Same the other way around (using 1 disables the other).

2. (hard to reproduce consistently ) .... Search results from the widget are sometimes wrong / inconsistent. Sometimes when I type in "ada" I get back only 2 rows - whereas typing the same 3 chars into Quick Search (upper left) gives more results.

May be upgrade to jquey ui autocomplete might fix this.
