When viewing the four main tabs in the tracker, the "report an issue" tab remains active when one selects it. Changing

/// submenus
switch ($view){
case 'reportanissue':
$page = '';
break;

to

/// submenus
switch ($view){
case 'reportanissue':
$page = 'reportanissue';
break;

in tracker/view.php seems to fix this. However, I did not follow whether there are any side-effects.
