Hi! Got a similar problem here.
I'm testing with Win7+Chrome and measuring memory with Chrome task manager and profiler.
Whenever I need to cicle trough a code like this, the grid is destroyed but the memory is never released.
$('#grid_container > #grid').jqGrid('GridDestroy');
$('#grid_container').html('
');
$('#grid_container > #grid').jqGrid({ ... });
Is there anything else that needs to be done to free the memory after destroying the grid (and before creating a new one)???
