Ajax toolbar, Undo icon not visible

[#1]

Hi,

I dont know whats exactly wrong with the settings & where exactly, but the Ajax toolbar is not showing the Undo & Redo button in toolbar.

With other qvw's its working fine. But not with this one specific qvw.

Can any body plz help.

I havent done any changes to the default Qlikview css neither am I using any extension objects.

Experts please help.

Thanks in advance
