Hi, from the sound of it that’s strictly a CSS problem and not something that could be controlled by the plugin. I can’t really say what might be done to fix it without seeing a URL, though, so if you’d like to provide one that would help.
My guess is the footer widget has a CSS float: or position: style applied to it – those can both cause an element to break out of the normal flow and overlap other elements.
If nothing else works, you could also switch the directions to ‘google’ which will open a separate window for the directions.
