There is no point including a selector if you just use a complete wildcard. Perhaps try using something else as part of your selector instead of title to select the correct element?
As for why it’s not working, is it possible that there is more than one chrome.exe widget open? If so, it won’t find it because it can’t differentiate between them without a title to find (or a more specific selector).
If that’s not it, please show a screenshot of what it looks like in uiexplorer when you click on the element
