Hmm... at this point I suppose it depends on what you are doing with your popup component. We'd have to see some code to try and pinpoint memory-leaks.
Are you creating a new popup everytime the user requests it, or do you create one instance and use the popup manager to show and hide that instance, setting data properties accordingly? Are you adding listeners to descendant components in the popup? If so are you using weak references? For example: addEventListener(MouseEvent.CLICK, onClick, false, 0, true); and not addEventListener(MouseEvent.CLICK, onClick) HTH, Ryan From: [email protected] [mailto:[email protected]] On Behalf Of Dmitri Girski Sent: Monday, February 09, 2009 5:37 PM To: [email protected] Subject: [flexcoders] Re: Memory consumption by the browser Hi Ryan, I tested it on IE7, Chrome, Firefox3, Safari (Mac). They all perform in consistent manner, Safari is less greedy, IE & FF are the most hungry ones. But as I said before, I can't see this footprint shrink when I minimise browsers. I even set this secret variable for FF - trim_on_minimise - no effect. How come?
