page builder: No save ability of widget information

Hello,
Really appreciate the vantage theme and I’ll buy it in the new year. However just updating my homepage, I have a circle icon widgets in the page builder and cannot now save any changes I make within the widget. The button labled done is edge higlighted in blue to signal its ready however when clicked it does not respond, the new widget informaton is not saved and I can only close the widget editor. Same when starting with a fresh widget. Also there are two close X’s in the top right, one misaligned in the grey strip at the top – this one works – and a blue cross with in the information pane itself – this does nothing.
There are also similar issues on a few other widgets, but not all.
Its a new problem, nothing has changed on my end.
Using Ubuntu 14.10, firefox 33

Hope you guys can help,

Rob
