I update the Chrome version to 14.0.835.186, but the problem persist.
And, Yes, the fop2 is working with other browsers.
I use fop2 on intranet, we don´t have filters to this network.

Chrome Version: 11.0.696.68
FOP2 Version: 2.20

until 2 days ago works fine on my pc, but with others the problem existed.
yesterday i clean my browser cache and after that get this problem with Chrome.
