Issue with column moving and save sort

I have a grid which has both save & load column order and save & load sort. I move a column and then sort this or some other column. I visit another page and come back to this grid, I find that sort order is applied to the wrong column, that is sort is applied to the column which originally had the same column number as sorted columns new position before we moved columns around and not to the intended column.

Any way to fix this?

This issue has been fixed at the latest version of dhtmlxGrid. Please update your files

I am already using 2.6

Is there a web page where I can see the DHTMLX releases, dates and what has been fixed in each?
