SplitAt + navigation

Hello I am using Dhtmlx Pro 2.6.
I am using splitAt and navigation functionality of dhtmlx.
If i have an grid with scroll,when I click on right grid and i use the down arrow, when overload the visible data, only the splited grid is scrolled to down, the right grid is frozen.

–This 2 components are incompatible?
–Is fixed on version 3.0?

Thanks in advance

Access/ExCell keymap functionality is compatible with frozen columns functionality.
Please, try to update the version of your dhtmlxGrid.
