Hi Jiri,
I'm not sure which AS version you're using but here are some good links
on garbage collection in AS3.

32000+ more links can be found by googling, "Flash AS3 garbage collection".

Hello List,
I have two classes Time and Clock, see below. To get good encapsulation,
in the Time class I added a function called clone(). This returns a copy
of the Time instance, instead of a reference to it.
Now I run the code, using an interval that calls the
Clock.getElepasedTime(). While watching the Memory I can see it build
up. Does this mean that with every clone of the Time object it still
holds a reference and therefore doesnt get deleted by the garbage
collector.
Hope somebody can enlighten me..
