Flash and the Back button

In my quest to remove as much of the "flash deveations" from webstandards, i made a brandnew backbutton handler.
I did this before with the flash version of www.adje.nl (now offline), but now improved on it.
You can see it in action at : Martin's site

I'd appreciate it if you'd let me know if it doesn't work with your browser...

I am now trying to get deeplinking to work in combination with this. Not easy but i'm getting there...
