dhtmlxGrid with IE9

Has anybody used the dhtmlxGrid with IE9?

I have seen some rendering problems:

  1. Hidden columns are visible.
  2. Data columns with different widths for distinct rows.

dhtmlxGrid does support IE9. Please make sure if you are using latest dhtmlxGrid version and Hot Fix for IE 9 http://www.dhtmlx.com/blog/?p=604

Thank you a lot!
