Removing tooltips from grid

grid.enableTooltips(“false,false,false”);

breaks the grid. Is there a different way of removing tooltips?

Part of code that creates the grid.

// Create grid grid = new dhtmlXGridObject('links_grid_'+card_id); grid.setImagePath("dhtmlxGrid_dnld/codebase/imgs/"); grid.setHeader("ID,Title,URL"); grid.setInitWidths("50,124,194"); grid.setColAlign("right,left,left"); grid.setColTypes("ed,ed,txt"); grid.setColSorting("str,str,str"); grid.enableDragAndDrop(true); grid.enableContextMenu(gridmenu); grid.enableValidation(true); grid.setColValidators(",NotEmpty,"); grid.init(); grid.attachEvent("onBeforeContextMenu", onShowMenu); grid.setColumnHidden(0,true); grid.setSkin("dhx_skyblue"); grid.enableTooltips("false,false,false"); grid.bF(false); grid.loadCSVString(grid_csv);
