I've just installed your new lib.
I've never got error messages in grid but with this function I've got.
It updates only small sets of bulks but always after few updates gets pop-up JavaScript alert with "500 : Internal Server Error. Status: error"

Turn errors on. Goto jqgrid_dist.php make it 'on'
ini_set("display_errors","on"); // changed from off to on
And check firebug's response for error message. If some updates are working, others should work too.
