Thanks for the video link. I've not had a moment yet to review it and attempt it but I will. I've been trying different methods with the .htc file but to no avail.... yet.
I've run into some other problems that I'm more concerned about and will have to post another ticket about.
I do have an update on the first question I had about hiding the menu on the home page.
I tried the code that Dude suggested in the avia.js file and it didn't work for me in Chrome or IE8 & 9.
I did find a solution though! I was able to make the menu hidden though by creating a page for the Front Page. I called this page "about". Then at the the bottom of the page, there is an option for Instant Gallery Background. I set this to hide the navigation upon loading the page. This method appears to work for Chrome, IE 8 & 9. I still need to test it though in other browser's.
