I live in Brazil!
I'm just a member of this community and very much like Renderosity given, mes feel at home and lodge my freebies here since 2003.
Regarding the problem with downloading a freebie and scroll bar, try the following, click on the desired freebie, wait for the pop-up window and wait a few seconds that your download will start automatically. Another thing is check your browser is disabled oseu to open windows Renderosity.

Have a good weekend!
