Hi All,
I think the error "Error # 101: Kantu is not connected to a browser tab” happens after a popup window is closed based on my experience (not sure if there are other cases though). Try downloading Chrome extension “Open link in same tab, pop-up as tab [Free]” (link:Open link in same tab, pop-up as tab [Free] - Chrome Web Store)
The extension will block popup window and open a new tab instead. I think this workaround will solve majority of "Error # 101: Kantu is not connected to a browser tab”
