Need help - Piecemaker 2/FireFox problem

Hello guys/gals,

is there any known issues with Piecemaker slider and Firefox that I am missing?

I have some kind of caching problem. Everything works fine and then the slider stops working saying 403 networking problem – access forbidden for the image in the cache folder. It is strange it only happens with Firefox and no other browser. I have added the ”?random_number” fix to the piecemaker.swf but still get the error every 3-4 hours.

Any help would be highly appreciated.
