hi,

I have one “main” swf that have a navigation. Navigation load external swf’s with Loader class. I had a memory problem and i focused it to one “swf page” so i deleted all others than two external pages from navigation.

First of them works fine, but all the time I opened the second one, memory takes 2Mb more memory. I remove all listeners in REMOVED\_FROM\_STAGE event so that’s not the problem.

Then I realised that in that “bad swf” is UIScrollerBar which graphics I have changed. If I delete that scrollerbar from stage and from libarary, that memory problem doesn’t occur.

Is there some invisible automatic listeners or what? I can’t understand what should I do? (that scrollerbar is linked with dynamic textfield)
