Horizontal scroll bar


I have a problem : i can’t scroll my gant chart.
I don’t have any scroll bar.
Is there something to configure to have it ?

For info, i’m using Firefox 34.0.5

On which device problem occurs ?
Scroll works fine for me while using FF 34 on desktop PC.

Sorry, i’ve found my mistake.
Problem resolved.
