Disappearance issue

I have an MC on stage with EFF effect on it..
It works well, the problem is when I go to different page and go back to the page with EFF, the MC simply doesnt show.. I tried removing the effect and it works fine but as long as EFF applied the MC shows only once.
Any ideas?

Did you try to leave the firs frame blank and add the flasheff starting with the second frame? Try to do that and see what's happening.

Yes i did. I read about it here somewhere and tried it but in vain.
What I do is fade each screen to alpha=0 and then remove from stage.. When I call the screen back to stage again the flasheff doesnt function.

What exactly are you removing from stage? Are you removing the flasheff instance?

Yes. I am removing MC containing EFF instances.

Then you need to add it again and set the effects and target all over again. If still doesn't work create a simple example, open a ticket and send us the source files.
