I found several discussions that hinted at my issue, but none that contained a solution.
I have a main page that contains a FLASH movie/Menu. The rest of the site is contained in an IFrame that gets filled when the Flash buttons are clicked.
Those pieces work as expected. On several of the iframe pages I have some movable panels that are Javascript driven. They work fine the first time the page is loaded.
However, if the user goes to another page and then clicks the back button, the panels no longer work. Likewise, clicking a flash button to go to another page and clicking the original button to return to a page also results in non-working panels. But, if the page is refreshed then everything works again.
I suspect that the issue centers around the iframe page becoming disconnected from the Javascript code.
Is there any intialization routine or page orientation routine that I could call to keep everything in sync?
