Hello,

I don’t even know how to explain this…

Ok, i’m developing a site, which has some flvs, dynamic masks, etc.  
Everything was working fine…

Upon creation of a new class/symbol, everytime i draw a simple shape (like a square), and then compile the swf, this shape appears distorted, like if it were in perspective.

What’s even stranger, is that if i delete this new class from the library everything is fine!

This new class has a sprite which is a dynamic mask, which in turn has other two dynamic masks. If i delete these masks from the library, no distortion occurs

All the other masks also appear distorted!!

I have no ideia why this happens…is there any limitations for the use of masks?

Thanks
