Paging module breaks other modules that also alter text in a post using hook_nodeapi

Holy smokes I solved it!!

I was right about the issue and the solution is amazingly simple once you fully understand the problem.

The core problem is paging is wiping out other modules hook_nodeapi "view" changes with this line.

$node->content['body']['#value'] = check_markup($node->pages[$page], $node->format, FALSE);

But fixing it would be a bear because you would need to rethink how paging works. All you really need if for the paging module to run first so that other module get the paged body to alter.

Currently the paging module has it's weight set to 0 which means it's hook_nodeapi call run in a mishmash with all others. (based on alphabetical order I think)

I added this update (below) to my paging.install file and then ran update.php on my site.
(fyi, I'm running dev and the latest update in my install files was for so I used _5 )
/**
* Implementation of hook_update_N().
*/
function paging_update_5() {
$ret = array();
$ret[] = update_sql("UPDATE {system} SET weight = -100 WHERE name = 'paging'");
return $ret;
}

Making this change basically makes paging run first and the problems disappear.

Good luck
