Problems with User Interface after installation

[Kirai]

Hi, I just installed Zentyal through a Xen. And the interface seems to be refreshing at a fast rate because I can't select anything inside the VM. At the machine startup a webpage opens, I can even click the webpage but it still goes away and comes back like every 2 sec.

Tried to install tools, though it seems it's not possible due to the same problem refered.

Any idea of what might be the problem?!

I've got mine working through Xen (debian distro) using Vmware image and then converting to raw image and made a normal config file for it.

So I don't get the GUI interface as I'm using PV setup but everything else works fine.
Browser interface is ok.

does every install has the same issue?
