dhtmlxGrid refresh memory leak

If you use the sources below, the memory will increase.

Please let me know what the solution is.

Must Use Internet Explorer 8 ~ 11.

Thank Your Help.

IE 8-9 doesn’t release XHR object until full page reloading, which means each ajax request will lead to extra memory consuming.
It can’t be fixed ( issue affects any AJAX library and is not specific for DHTMLX )
