jQuery Grid Plugin - jqGrid

jqGrid3.5, Firefox 3.5.5

I am evaluating creating grid for about 35 editable columns in a row. Setting

}).navGrid('#pager',
               { }, //options
               {bSubmit: "Save", addCaption:"Edit Row", height:500, width:450,reloadAfterSubmit:true, modal: true, closeAfterEdit: true }, // edit options
               {bSubmit: "Save", addCaption:"Add Row", height:500, width:450,reloadAfterSubmit:true, modal: true, closeAfterAdd: true }, // add options
               {reloadAfterSubmit:true}, // del options
               {} // search options

This causes the form dialog to show a somewhat truncated scroll bar on the right, Save/Cancel buttoms are not shown.

Resizing the form by draggng the bottom right corner shows more rows - but I run out of space on the desktop.

Is this  abig or some config mssing on my part?

thx
