Rapid weaver won't open a new window

I’m using Rapid Weaver 7.04 for Mac (OSX 10.11.6).
I’m setting up a link to open my Facebook page on my website.
I have activated te button “open in new window”.
When I publish te website, the link will be activated, but not in a new windows.

I have tried it in Safari and in Chrome, but there is no deference.

Can someone help me out?
