Memory Issues

programming flash
1

Hello im having a memory issues with my flash file. In IE i open a separate browser with just the website and flash file so nothing else interfers. IE started at 28mb on load within 6min it was at 90mb of ram and still going up. i hit refresh back to 28. Firefox must flush its memory because it goes up when the picture changes then goes down shortly after.

i know people wont sit at the homepage for 6min in most cases but i still dont want the memory problem. ANY IDEAS?
