Green Boxes appear in my animation. How to get rid of them?

[Melkboy]

I use Adobe Flash CS3. What are those boxes and how do I get rid of them?

Btw: It happens when I export it to any format.

Can you show a screenshot of these green boxes?

These are appearing in your published file or are they only in the fla?

[Melkboy]

These appear after I have published/exported and are not visible in the program itself.

I can't be sure how your response aligns with my question since you used different terminology.  If these are appearing in the fla, I could understand that maybe some feature was turned on in the Flash UI, but I cannot explain what causes them to show up in the file you publish.  Maybe someone else has some idea?
