I have uninstalled latest GW and installed an older version 3.5.501 that comes with the old UI and I could immediately see two WebViews upon running uTorrent and the Weather app, confirming my past experience.
However, I remember that it was always unpredictable and frustrating. I posted several threads in these forums regarding the various manifestations of the issues I experienced. I would have to clear them all from time to time, because some app would not work, which was rather unexpected, because I would recall that it had worked previously.
Anyway, it seems that this experience was just a COINCIDENCE, because right now, I noticed (upon hovering the items) that these are TWO DIFFERENT VERSIONS of the WebView for some reason, so any past experience that I could block some apps, while keep some apps connected, was probably just a coincidence due to different versions of WebView being used under the hood.
Anyway, after installing the new version again (3.7), when I run the two aforementioned apps, I only ever see one WebView app in the list, just a few minutes later than my previous test - strangely it seems to only use the same version now.
