observe_form should only react to changes in the form

I have a problem with observe_form:

<%= observe_form( "search_form",                   :frequency => 0.25,                   :update => "search",                   :loading => "Element.show('spinner')",                   :complete => "Element.hide('spinner')",                   :url => { :action => 'update_search' }) %>

In my form I have a combo box. When the user clicks the combo box and scans through the options (WITHOUT yet selecting one), the controller action gets called by observe_form. This is pretty annoying. What I intend is that the action is only called once the user really clicks on an option (thus changing the "model data" of the form if you want). How can I only react to "real" changes of the form and ignore everything else?

I already tried the ":on => 'click'" option, but 1) this doesn't seem to work and 2) it is a nasty workaround keeping the user from using my search form with a keyboard.

Any ideas?

You should remove the :frequency option.
