datagrid's horizontal scrollbar scroll too slowly.

when datagrid has many columns, datagrid will show horizontal scrollbar ,
e.g: dhtmlx.com/docs/products/dhtmlx … iline.html,
but when click on the horizontal scrollbar’s arrow or scrollbar’s space, the horizontal scrollbar will only scroll several pixels, the scroll step is two small, is it possible to adjust the scrollbar’s step?

thanks!

That issue was fixed in the latest version of the dhtmlxGrid.
Please, try to update your dhtmlxGrid files.
