for users who come across this i have discovered a new work around.
You will need to create a new php internal page with the following code
Code:
<?php
/*
Write code inserting output inside
variable $content as in following example.
You have DB connection, all global vars
and all MKPortal and Forum functions at your availability
*/
$content="<iframe src =\"http://yoursiteurl/arcade.php?\" frameborder=\"0\" width=\"100%\" height=\"1000\" scrolling=\"yes\"></iframe>";
$mklib->loadcolumnright = 0;
$mklib->loadcolumnleft = 0;
?>
Then you can add the page link to your mkportal navstrip
