Grid CellClick handler has bug when a column is hidden

I have a grid where the first column is hidden, when the click event fires as below the column object is always one column out ie. it returns the column next to the one that was clicked."CellClick", function(row,column,e){

If I make the first column visible then all works as expected - looks like a bug to me.

Thank you for your post.
The problem is confirmed. We’ll try to fix it in future updates.

That problem was fixed in the dhtmlxGrid 6.4.3 build.
Thank you for your report and the patience.
