The windows position is not correct when the windows’ location is out of the current explore window in the IE, But it is right in firefox, and why??

Here is your approach in the attachment: you need to set right viewport.
Read more about it here: docs.dhtmlx.com/doku.php?id=dhtm … s#viewport

About messages: they aren’t ERROR, they are WARNING. It is browser’s behavior.
