Strange red square showing up in .swf?

I'm making a pretty simple flash animation for work not using any actionscript. I'm importing layers from a PSD to do it.

When I'm working on the .fla I don't see anything unexpected, but when I view the .swf or export it there's a little red square in the animation. It moves with some of the stuff I have moving in the animation like they're attached somehow, but I can't find it in the fla to get rid of it.

Any help?

my first thougt was that you imported a 'project' file (.psd) but i just tested that and it works fine since you import specific layers from photoshop.

cant help you unless you upload the .fla or show some pictures of what your problem is.
