Hi Roman, You describe my_var =null as being useless, but this should be enough for the garbage collector to come along and reclaim an object? With respect to the static issue, what do you mean with 'static instances' ? Could u provide an example of such an object with isn't reclaimed?

Oh my, this really is a matter in Flash... Since we have often experienced variable's values not being cleared after use, we do the following: my_var = null; // This first step probably is useless, but ALWAYS use DELETE! delete my_var; If the value contained within the variable is a movieclip, then make sure that this mc has an "onUnload"-handler that does the above with all variables and to avoid instances from floating in memory after having deleted, unloaded and removed them, if possible don't use static values! I have made the experience that static instances stay in memory after there is no reference to them left, since I set them all to null and then deleted them. Then, when I re-create an instance of such static stuff, it isn't created anew, but Flash uses the old piece that rests in memory. Maybe it's just that I don't really, really understand the concept of "static", but I know it can lead to unpredictable and hard-to-track errors.
