Do you really need the normal buttons (with 3 states: over, up, down) or are shape buttons acceptable (have only 2 states). I'm asking this because of several reasons:
- shape button can be customized inside Captivate without need for a graphical application
- shape buttons can be filled with an image if you do not like the basic shapes with text inside
- one shape has immediately the two states (up and pressed), you don't have to create two images
- if necessary they can be timed for multiple slides or put on a master slide, which is not possible for the default buttons.
The template I plan as a successor for CP6 (see blog post I referred to in my previous answer) will certainly use shape buttons. In that case your goal will be achieved much easier:
- create shape buttons in blue, I'll label them Bt_blue_x (x is the number: 1, 2, 3 or 4), you only have to mark the option 'Use as Button' in the properties panel for a shape
- duplicate those buttons, use SHIFT-LEFT, SHIFT-UP to put them in exactly the same place as the blue ones
- change fill of those duplicates to red, label them Bt_red_x and make them invisible in the Properties panel
- add the simple action 'Jump to....' to those red buttons
- when a button Bt_Blue_x is clicked execute a standard advanced action that will be like this:
- Hide Bt_Blue_x
- Show Bt_Red_x
- Jump to ....
- Duplicate and edit that action for each Blue button (to change the number)
That should work, because it is now possible to have two interactive objects in exactly the same place at the same time and to toggle their visibility (was not possible in previous versions). I only very seldom use the cumbersome image buttons since CP6 appeared. Too much work...
And if you want to give the users the opportunity within the file from start, group both Blue buttons (Grp_Blue) and Red buttons (Grp_Red) and add this action to Enter Slide event:
- Show Grp_Blue
- Hide Grp_Red
