Can't type text into combobox in gridcell with IE(10) in 4.0

Suite and Optimus Suite 5
#1

When clicking into gridcell with combo, list will be displayed, but when trying to click somewhere in the inputtextbox focus is lost on mouseup. So it’s not possible to type any text into Combobox for new value or filtering.
With Firefox the behaviour is as expected, with Chrome it’s same issue as with IE10.

When clicking on the button of combo, list opens on mousedown an closes on mouseup. With firefox its vice versa - list closes on mousedown and opens on mouseup instead of opening with first click and closing on second click.

I’m just upgrading from Version 3.6 to 4.0.3

[code]

test grid with combo
var cbitems = new Array(2); var cblist = new Array(3); cbitems[0] = "1"; cbitems[1] = "John Grisham"; cblist[0] = cbitems; cbitems = new Array(2); cbitems[0] = "2"; cbitems[1] = "Stephen King"; cblist[1] = cbitems; cbitems = new Array(2); cbitems[0] = "3"; cbitems[1] = "Honore de Balzac"; cblist[2] = cbitems; 
    mygrid = new dhtmlXGridObject('gridbox');
    mygrid.setHeader("Sales,Author");
    mygrid.setInitWidths("100,250");
    mygrid.setColAlign("right,left");
    mygrid.setColTypes("ed,combo");
    mygrid.setColSorting("int,str");
    mygrid.setSkin("dhx_skyblue");
    mygrid.enableEditEvents(true, false, false);
    mygrid.init();
    mygrid.loadXML("codebase/grid_authors.xml");
    mycombo = mygrid.getColumnCombo(1);
    mycombo.enableFilteringMode("between");
    mycombo.addOption(cblist);
</script>
