Scott, There is not a specific type of application, it is more the use of leveraging DOM in combination with JavaScript.
I showed you a small teaser from an upcoming CMS, using a rich interface. That interface is build up with JavaScript. Each menu, treeview, and table consists out of OO JS, which provides sorting, drag n drop, on demand loading, single paged interface, etc, etc. Then we also have a layered presentation model, also entirely based on Javascript, with ui persistency layers, reusable scripting etc. In general this interface is about 85% javascript and only 15% initial XHTML markup code. Even though a full refresh only leaks 50kb, an amount which is very normal regarding references to DOM. Will you notice this in terms of speed of the application, NO. Garbage collection is always a topic, whether you use Java, JavaScript, .NET, Actionscript; The way memory is released, if you have closed database connections, or methods of optimizing memory usage too prevent long and painful GC flushes. Managed languages never guarantee optimal use and release of memory. In theory they should, but in practice that is not reachable because there are too many complex parameters involved.

Micha, I'm at a crossroads, in that I typically defensive code when in DHTML (or any language which has auto-garbage collection enabled) - yet i'm concerned its an un-needed amount of work... ie reminds me of writing 115 lines of code to print "hello world" - sure its Zen powerd to the 10th degree - yet seems like i over did the task. I guess what i was asking is that what kind of application or if any out there that are being used suffer from this leak issue? and is it really an issue or like you stated with flash, happens but really not many notice only us perfectionists ;) On Tue, 8 Mar 2005 10:14:30 +0100, Micha Schopman <[EMAIL PROTECTED]> wrote: > Dave, > > There is no massive leak if you clean up before you leave the room.
