[SOLVED] Console visual problem in web portal of Proxmox VE 3.1

Hello,

I've installed Proxmox VE 3.1, managed to connect to the web interface, created a VM for a lubuntu 32bits, started it, opened a console from the web interface, then i tried to open a Terminal and got the following:



The Terminal is hard to use as i can't see the commands i'm typing ...

Is there a way to avoid this visual glitch ?

PS: I'm running the console from a WindowsXP 32bits, java7, firefox 26
