The AC will only remain in memory if there is a reference to it from somewhere in the app. If the TW is gone, so should the DG, and therefore its reference to the AC. If the AC was loaded into a var in the main app it will stay around. So, it depends on how you wrote your code.
Note that GC is opportunistic so the AC may not be collected until much later. Green Grapes go pretty far and are less messy to clean up. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of candysmate Sent: Wednesday, August 29, 2007 7:45 AM To: [email protected] Subject: [flexcoders] Stupid question - get ready to throw fruit.
