DHTMLXGRID about gridAlterCSS() function not works in IE. bu

I have created DHTMLX window it contains DHTMLX TabBar and Tab Contains DHTMLXGRID, And I have use gridAlterCSS() functoin for applying alternate coloring to row. Same is working very well with MOZILLA browser but not with IE Browser.

Please give me solution.

The base functionality works equally in all browsers, if problem still occurs for you - please provide a code snippet used for AlterCss mode enabling.
Beware that setSkin used after alterCss command may change its functionality ( each skin has predefined alterCss settings )
