hey there.

I am using the [kirupa.com](http://kirupa.com) technique for popping windows from flash. Works great!!

One thing happens sometimes though and I can’t figure it out. the flash inside the popped windows is sometimes offset abotu 20 pxls x and y, so it’s shifted right and down off-centre, cropping the bottom right part of the flash movie.

Any idea why this is happening? I am at a loss! thanks for any help 🙂

Make sure the HTML page you open has it’s margins set to 0. Those offsets are your page margins 🙂
