Scroll Problem

[Tsiangana]

-<-div style="overflow: scroll; border: 5px solid black; height: 800px;"->-

This style scroll that you used is causing problems in the app, for people who use Firefox browsers it creates two scroll bars, one vertical and one horizontal.

To solve this, just replace the code above with this:

-<-div style="overflow-y: scroll; border: 5px solid black; height: 800px;"->-

only change de overflow for overflow-y, this change can fixe de problem...
