Space and arrow key 's not working in latest download

In grid with simple text editor (ed) i cannot use the space or arrow key’s

It is only in the latest version of the dhtmlxgrid package.

I tried an older version and it worked fine.

Please help me out,

Please get the latest package from …, the version which you download was incorrect one, and already replaced with correct files.
