Re: [Dynapi-Dev] DynLayers elements not destroyed.

[Doug M. <do...@cr...>]

How did we recycle in NS 4?
While the memory leak was never completly fixed in NS 4,
we did manage to minimize it somewhat..
Keep in mind that the content of a layer in NS 4 is also retained in memory.
Simply calling setHTML() repeatedly on a layer in NS 4 will cause a memory
leak.

I never did find a solution for this.
The best I was able to do was reduce the amount of content that was being
set each time.
