e_baggg,
    You're not the only one. We're experiencing very similar problems.
Our app just keeps gobbling memory until the browser crashes. We've had
to resort to calling dispose() explicitly on every <mx:Image> and bitmap
we ever instantiate, and explicitly calling removeAllChildren() on every
contaniner before navigating away from anything. Helps a little. I'm
going to look in to the link you mentioned. Maybe that will help us a
little more than it has for you (fingers crossed).
 
Let us all know if you find anything else out.
 
Blake

Subject: [flexcoders] Memory issues ... garbage collection only running
in IE (not FF or Safari)



So I have an app in production which after 10 minutes of usage began 
to perform EXTREMELY slow, and users had to restart the app. (Flex 3) 
Windows and Mac...all browsers. I did some Profiling and did not get 
far. Whenever I take a Memory Snapshot, gc() is forced and all my 
objects are correctly removed from memory. So why are they not gc()'d 
in normal runtime?? I know gc() only runs when new memory is requested 
and nothing is being drawn/rendered. Both seem to be OK on my side.

I have read extensively all the blogs and Adobe docs regarding this 
issue, including the event listener for ENTER_FRAME which calls 
System.gc() twice. (http://www.craftymind.com/2008/04/09/kick-
<http://www.craftymind.com/2008/04/09/kick-> 
starting-the-garbage-collector-in-actionscript-3-with-air/). This 
unfortunately did not work for me. 

To simplify, I created a simple app that adds and removes RichText 
fields. if I create 50 of them, then remove them all, then Add one 
back, that *should* force a gc() but it does not. The FF memory always 
stays high. I noticed in IE, minimizing the browser window causes a 
gc() and my memory drops to a much lower #.

Has anyone seen or come across this? B/c of this issue, we're pretty 
much going to lose our customers and try to wing a html/ajax app 
ASAP..so I'm scrambling to resolve this. 

Thanks in advance for any help.
