VM Startup/Shutdown Settings using Web Client 5.1

Hi,

I am trying to configure automatic VM startup with ESXi host startup. In Web Client, i selected the host then Manage>Settings>VM Startup/Shutodown. In the VM Administration guide it's stated that i should click on the Edit button. However, this Edit button appears for less then 1 second then it disappears!

I tried using IE 9 and Google Chrome, but i'm getting the same symptoms.

Any suggestions?

Thank you
