Need help: gallery elements not loading on first click

I am loading individual swfs into a container in my photo gallery. I use a button event to load each swf. The first time I navigate to the site and select a gallery album to view, some of the elements do not load, usually the static text title, and sometimes the scrollers on either side of the the thumbs. If I navigate back and select the same album again, everything displays properly. Also, once the site is cached in my browser, this doesn’t happen.

You can see this yourself at my site:

Click Enter and click on Gallery to see the different albums.

I can provide more on my code, etc, if needed, but I’m hoping this is a “duh,” easily remedied.
