When you select several items (with the property Visible=True) and then set the property 'Visible' for example to False then you would expect that all the items are Visible=False after you did this. But all items are still Visible=True so you have to change that property all seperately.... (Simple shadow for example works fine!)
Strange, I tried it again, still not working .....but when change it and then set for example click on Custom Code and select 'nothing' (This is a second action) the the visibility is changed for all the items??!! Petran can you test it again with only one action, so only the visibilty item?
Just tested it on a new page. All the selected items change on visibility. I tried to reproduce your problem but I can't. Very strange indeed. I suppose you are also using version 4.2.53?
