--  <?$PHP_SELF?> is incorrect - that produces nothing.

You should use <?=$PHP_SELF?> or <? echo $PHP_SELF ?>, this produces the
path to the current file.

The reason it doesn't work on some browsers is because they do not action
the form to itself by default, ie. if there is nothing in the action
attribute. Some browsers do.
