'Add property' hangs completely

[pnatsiavas]

I deployed the Windows binaries on a cloud VM on Windows Server 2012 using Virtuoso 7.2 as a back-end to explore OntoWiki. My VM has 8GB and despite that, OntoWiki is a little bit slow. However, when adding a property, OntoWiki hangs.

On Mozilla Firefox, I get a grayed screen when I click "Add property" on a specific resource.
On Chrome, I get an infinitely working javascript "Loader" animation.
I had the same behavior when trying to add "Admin" password in the fist steps of my installation.

I can see no errors on the server side log (I have already enabled the "debug" option on the configuration) and I can only see "deprecated" messages in the javascript console.

Please note that I could provide access to the VM in order to debug the issue.
