[Seaside] How to create a new browser window

[Richard K Eng]

I was wondering: how can I create a new browser window from within a Seaside 
app?

Right now, I have this method,

view: item
        WARenderLoop new call: (GSViewer new path: item path; yourself)

that brings up a new webpage, but I'd like to open it up in a new browser 
window instead. (FYI, #view: is invoked by clicking on a clickBlock in a 
WATableReport.)

Thanks,
Richard
