I have the "Value Not Empty" rule in effect, but some users are entering spaces in the field instead of typing a real response, and it is getting past the rule. Is there a way to force them to type something other than the spaces?

Go to Components > BreezingForms > Manage Scripts and then click on the value_notempty script to edit it.

Now replace this:

function ff_valuenotempty(element, message)
{
     if (element.value!='') return '';
     if (message=='') message = "Please enter "+element.name+".\n";
     ff_validationFocus(element.name);
     return message;
} // ff_valuenotempty

with this:

function ff_valuenotempty(element, message)
{
     if ( ff_trim(element.value) ) return '';
     if (message=='') message = "Please enter "+element.name+".\n";
     ff_validationFocus(element.name);
     return message;
} // ff_valuenotempty

Then click on the SAVE icon in the lower right-hand corner of the screen. Test it out -- it should work for you now.
