Edit Action in Activity Harmony 650

Hi,

Just been reading through the forum, seems like there are a lot of people in the know.

I have just setup a Harminy 650 using the online silverlight based software..

The activivity I want to edit is to watch a movie on my HTPC..

I am running a Zotac AD12 through a marantz AV rec into my TV..

The remote works sweet however it insists on powering up and down my PC, which I do not want it to do ( as it stays on downloading etc).

I cannot edit this for some reason however, there is no Pencil icon next to the Power on function in the dialogue box.. How do I cancel this command?




Thanks in advance,

Sam
