well it depends on what these are doing - if you have 'repeating' actions you
might be able to use a single tween within a method and pass the instance to
tween. but in any case if you do not need to 'know' if the tween is complete to
initiate the next action, you can call the constructor without assigning it to
a var.  i don't think that either way will effect memory though - it's more
about the quantity in this scenario.

ok - well that sounds more like you have either something that is 'still
running' like a onEnterFrame event - or if these items are moved off stage they
aren't getting 'removed' from the timeline - or a number of other things that
could cause a slow down.  like for instance - if all 50 of these items are
being 'brought to' the stage - that's quite a few things to be on there at the
same time - or if they have a great deal of alpha transparencies or gradients
this will also cause a lag.  also, if your using AS3 and have added Listeners
to items, these will 'pile up' if you don't construct methods to remove them
from the event list.  so it could be a number of things really - if you could
post your file we may be able to pinpoint the problem.
