I believe you need to avoid doing this in your Layout Ready event. Why are you not showing/hiding the subforms in their Initialise events?

Just a quick thought, would the Maps API for Flash be an option? Obviously would need the next version of Livecycle Designer?

Using the layout:ready event to show/hide content is a risky business, I have seen inconsitant results in the past, works in one place and not another.According to the manual ...Note: Scripts that fire on layout:ready should not do anything that would cause the layout of the form to change. For exam...

Do you have any problems when saving across different versions of Adobe Reader?We are experiencing problems when saving in 9.0 and opening in 9.4, and vice versa.
