We have a web based flash application which makes soap calls to our server end. We are seeing a memory issue in IE [7 and 8] with adobe flash playe 9 when we keep the window open for a large period of time. This issue causes a long delay of more than 30 sec in browser sending the soap requests. We also noticed when the security level is scaled down to medium from medium-high in IE, this issue is not visible. but that is not an option for us due to corporate policies.
