Autocomplete - Stop Rollover+Return submitting data

Autocomplete - Stop Rollover+Return submitting data

Hi all,

I'm using JQuery Autocomplete (bassistance) and have run into a problem.
If the mouse rolls over one of the autocomplete suggestions and the user hits the return key (rather than clicking to make selection), the form is submitted and goes to whatever link was rolled over at the time.

This is a problem as people click in the textbox, and when typing their search, leave the pointer where the autocomplete popup appears.  So when they hit enter, it doesn't do the search for whatever they typed in the box but whatever was highlighted in the autocomplete suggestions.

Is there a way to stop this?
