jQuery Grid Plugin - jqGrid

Hi.

I'm experiencing a problem with edit form.

When i click on pager's add or edit button, the form resize (in height) "gbox_xx" div pushing down the table (i can see the background of gbox behind the form)

I can move the form but the "gbox" still be resized.

I see a difference with demo : the form is rendered in the gbox div in my example but directly in body in the demo.

Also, i'm using jquery 2.0.3, jqueryui 1.10.3, maybe it is due to this.

I'm also using my jqgrid fork, but the problem is the same if i change it with jqgrid official master on github.

I've found a solution by adding 'ui-dialog' css class in grid.common.js -> createModal -> mw.className

Someone experienced this problem or see another solution ?
