I am having the same problem. Has it been resolved?
Groupy works great in all my applications, apart from chrome.
Is this a known issue?
When I try to group chrome browsers together nothing happens.
When I try to group Word, for example, to a Chrome window, it turns blue, as usual, but says 'cannot group a window that is not responding'.
I have tried purging and several other 'fixes' with no luck.
