The "notify" button is usually at the top and at the end of the page, not one for each message, to make them visible at low resolutions you can add something like:
a.linklevel1.button_strip_notify,
a.linklevel1.button_strip_send {
display: block !important;
}
to your custom.css file (and if you don't have a custom.css just create and upload it to the theme directory.
