in the admin-personal-setting-area you could mange the groups in which a user is. There is shown a list of all groups.
In FF and IE there is a real list, but in Opera there is a single line liste with arrows top and down - but for multple selection you do not see, what groups are marked, you have to scroll for every group.
solution: say to the browser that it should shown at least 5 groups or so:
functions_installer.inc.php
line 391 f: add size="5"
Code: Select all
case 'multilist':
echo '<select name="'. $name .'[]" multiple="multiple" size="5">';
