I purchased gravity forms today and noticed this problem. I am not sure where to report it.
I noticed the qtip javascript and the css files are included on every page of the admin instead of within the gravityform pages. Theres already a function to handle this so it is an easy fix.
On tooltips.php at the very top change
add_action("admin_print_scripts", 'print_tooltip_scripts');
to
if(self::is_gravity_page()) {
add_action("admin_print_scripts", 'print_tooltip_scripts');
}
