I am just upgrading to FW4 and some functions seem to not work as in FW3.5.
I am trying to make roll over function to the button, but for some reason, the “add action” symbol gets greyed out when I activate another “mouse over” button…
One or more of these elements are layers, then. Select all elements you want to be a part of a single Rollover, then Group them (use the menu, Apple-G is the wrong shortcut).
You will be able to add the Rollover Action to the group, and all grouped elements will appear as separate options in the Images tab of the Actions palette.
