In 7.3.1, I noticed that if Chrome (my default browser) is running but no browser window is open, if I click on the URL in the website field in a 1Password Mac item, nothing happens: a new Chrome window is not opened. If a Chrome window is already open when I do this, a new Window (well, tab) is created with the URL loaded. Or if Chrome is not running, then Chrome will be launched and a window opened with the URL loaded.
The behavior only occurs if Chrome is running but no browser window is open.
I recall posting about a similar issue quite some time ago. It was fixed. Is it back for an encore?
